Two sides of the coin


In the early '90s police detective Phil Cleary was forced to let go of the thief. He knew that a person is guilty, but was unable to gather sufficient evidence for the court, then Phil thought - it would be nice if the suspect himself "gave himself away».
Phil Cleary shared his thoughts with his brother Mike, a chemist by profession. Mike was involved in scientific research and in a few brothers created a company SmartWater - «Smart Water».
8 years ago, on Valentine's Day a few well-known, but do not catch thieves venerable London received a greeting from a mysterious admirer. In the frame of pink hearts and kupidonchikov were poems: «Roses are red, violets are blue, when SmartWater's activated, it's over for you» - «Roses are red, violets are blue, when the" Smart Water "activate - you end».
Sent out postcards British police chief Vicki Marr, a woman with a sense of humor.
So what is a "Smart Water"?
This is a completely transparent liquid is colorless and odorless, in which a small amount of floating particles invisible to the eye millions.
At each applied a unique engraving, identification number of "smart water". This number can be read using photomicrographs. It is unique for each subject, which the owner intends to protect.
Liquid is sprayed and leaves no visible traces. The microparticles are so small that they adhere to all surfaces, hammered into the smallest cracks, so that even if long try, then remove them completely fail.
Police suspect enough to shine ultraviolet light, if he had to deal with the encoded things, the skin and the clothes will fluoresce green and yellow.
Micrograph reveal the number of "smart water" so that a police database can identify the owner of the missing things, what is that thing, and so on.
SmartWater company produces and sells labeling kits and a monthly subscription for database support.
In recent years, police stations themselves are buying thousands of kits and distribute to residents of their districts, hoping to bring down the level of theft. On the doors of the houses treated with "smart water" - bright stickers with a warning. Police said that such prevention works.
Professor criminologist interviewed 100 venerable "burglar", 74 of them said that the house with a label they climb does not make sense.
Recently, the "Times" published a photograph of 28-year-old Japhet Askale. Actually, not one, but two photos. One is made in ordinary light, the other under ultraviolet. The ultraviolet images of Mr. Askale head glows green.
Invisible and imperceptible portion of "smart water" Mr. Askale got out of the car when the stolen laptop. At the trial it became clear that this car - police bait that laptop specifically left on the seat for his criminal temptation.
With this in mind, the judge punish the perpetrators to the fullest extent of English law - 49 hours of community service, plus payment of court costs in the amount of 400 pounds.
Severity of the sentence is not important here, and a hint of plotting to steal all, the message - do not, it's not worth it, because the invisible markers "stain" the whole chain from the attacker to the buyer-up.
It is said that the attackers were not in debt. There are rumors that they are buying a "smart water" with his officially registered encoding, and sprayed her the wrong thing, that is what they wanted to steal.
Then you can go to the police and demand analysis of the particles and on this basis to demand the return of their belongings.
Can be dramatic crease hands - yes I do grandfather left!
