Background technology

In recent years, the urban construction paces were accelerated, and the city scope constantly enlarges, government's " taboo is rubbed " policy is put into effect, " reasons such as " move back the city and enter the garden ", electric bicycle progressively becomes resident's main walking-replacing tool on and off duty in industrial enterprise.Yet in electric motor car vehicle quantity surge time,, prevention awareness but a little less than the relative thin, is effectively strengthened, and the phenomenon that arbitrarily parks cars is very general, thereby the stolen phenomenon of electric motor car is also serious further.According to statistics: in year July in January, 2006 to 2007, certain institute of basic unit accepts and the theft electric motor car case of prosecuting just has 37 48 people, accounts for 20.5% and 18.4% of all kinds of larceny cases, is only second to " stealing " case that occurs in the public place; Certain municipal court in January, 2009-November, trial " two rob a robber " case is 199 altogether, wherein steals and robs 70 of electric motor car cases, accounts for 35% of case sum.

The multiple analysis of causes of theft electric motor car case

At first masses' prevention awareness is weak, does not know perhaps how this takes precautions against, and is the auto theft case subjective condition that provides occurred frequently.When the personnel in charge of the case asks about the injured party and why not notes strengthen taking precautions against; The injured party often claims oneself to handle affairs only need be for a moment; Perhaps think the roadside People are hurrying to and fro and can not have things stolen; See that perhaps the parking area stopped many cars, thereby think not have what problem, and this has exactly given offender's opportunity.

The precautionary measures fall behind, and risk prevention instruments is single.At present the main people's police of dependence, joint defence team member and security personnel's patrol are taken precautions against by community, because wide, line length, people are few, are prone to stay the patrol blank spot, and effect is limited.The public place also gives the offender with opportunity because the volume of the flow of passengers is big, personnel are complicated, negligence of management, precautionary measures shortcoming to a certain extent.Have leak in community management especially, incidence of cases is lower in newly-built, the management regulation sub-district, and the old community of some open types incidence of cases is higher.Some sub-districts do not have the garage, and the resident can only be parked in electric motor car in the stair-corridor; Though what have has a garage, unattended, has opened convenience to the suspect.Though the people that has who has keeps an eye on, mostly old, be not good at managing even find that a suspect passes in and out also and will not bother about, make the burglar advance unopposed.

Anti-theft technique is simple, and the crime success ratio is high.Because manufacturer is for reducing cost; Do not pay attention to the research and the setting of anti-theft technique; Vehicle self theftproof performance is relatively poor, and the offender only need carry simple tools such as screwdriver etc., at short notice even can an electric motor car be stolen in one or two minute; The theft technical difficulty is low, process short, and it is fast to flee the scene.

Channels of stolen goods disposal are unimpeded, and the crime income is higher.Some underground vehicle transaction places, maintenance stand and waste and old article purchase spot are engaged in the illegal vehicle business silently, have in addition form network, channels of stolen goods disposal are unimpeded; And the electric motor car price is higher; The huge market demand, a stolen car is easy to slip out of the hand for three or five hundred yuan, has objectively stimulated robber's car case occurred frequently.

The characteristics of theft electric motor car case

The time fixed-siteization.From the incidence of criminal offenses place, mainly concentrate on the public places such as hospital, residential quarter, large supermarket, the market of farm produce and Internet bar that management is loose, strick precaution is not tight.See from the time of incidence of criminal offenses, mainly concentrate on noon and night.The crime place that the offender selects is food market or supermarket without exception, and the time all is chosen in the pedestrian about at 12 o'clock at less noon or after at 9 o'clock in evening.The offender stares at the car owner, and the shopping of generally buying vegetables is wanted 10 minutes to 20 minutes at least, as long as car owner one leaves, crime is difficult to come to light and arrest at once.

The crime means variation.From crime means; The offender adopts bolt clipper to cut off lock set perhaps to disclose unlocking tool with key; With the method for the making contact electric motor car that drives away, perhaps pry open the method for lockset again, also have minority to omit the program of picking lock with spanner; Directly transport electric motor car is whole with means of transports such as automobile, tricycles, the various and maneuverability of crime means improves greatly.

Stolen car flows to localization.From the situation of solving a case, stolen vehicle all in the local zone, is still kept intact basically, and the overwhelming majority also is in user mode, and it is rarely found that stolen car flows to the situation of other provinces and towns.Because transportation cost is high and risky, therefore, all dispose of stolen goods basically in this locality.Not positive reporting a case to the security authorities after many citizen are stolen also has many citizen from offender's hand, to buy stolen car with comparatively cheap price because of coveting little advantage, thereby makes the locality form bigger stolen car covert transaction market, and constantly develop.People's this passive attitude has also been encouraged offender's arrogance of crime again and again.

Case-involving crowd's compartmentalization.From the criminal native place, have tangible regionality, nonlocal population becomes the external people at highest risk of whole city's theft electric motor car crime.
