A rash of bike thefts in Austin, Travis County (and probably many major cities) has prompted Austin Police Department to focus on Bike Theft crimes downtown, by leaving high priced bicycles at street poles, fences, and sidewalks across the city -- unlocks and unguarded.
Many of these "bait bikes" are left on Campus at UT, and all are equipped with a tracking GPS linked to Austin Police computers.
While some might be locked with a cheap chain or other minor security measure, many are merely leaning against a bike rack, or wrapped to a light pole by an unlocked bike chain.
So what happens when someone decides to take one of the expensive, new bikes? Well, Austin Police tracks the movement and and swoop in for a Theft Arrest. And, since the bike is expensive (typically around $650-800), and since they include the price of the GPS unit which is attached to the bike (and likewise stolen -- valued at nearly $400), the grand total of the Theft gets the person to a Class A Misdemeanor Bike Theft.
So the first thing people say, is: Entrapment! Unfortunately, Entrapment is a very narrow defense, meaning it's only available in a few cases. Theft in the above described situation would NOT be able to take advantage of Entrapment, because, put simply, the person was free to merely walk away. There was no trap that forced the person to act illegally; instead, the legal course of action would have been to keep walking, which the person was free to do.
A potential defense, although not a good one, could also be Abandoned Property. The problem is that an Abandoned Property Defense requires the person finding the property to do several things BEFORE taking the item, such as (among other things) trying to find the rightful owner. While an Abandoned Property defense could work, more information and investigation would be needed to show that there was no Theft.
The best option, now that you know the dangers of Bait Bikes, is to avoid the bike at all costs.
