To be clear. The kid was not 'booked as a common criminal.'
He was not handcuffed, placed in the back seat of a patrol vehicle, taken to the county jail, fingerprinted, had booking photos taken of him and place in lock-up until he saw a judge.
The police fingerprinted him because they have the responsibility to be able to identify a suspect. Since the kid was only 11 years old and didn't have any form of ID on him at the time, a (single) fingerprint was taken so they could identify him a later time.
If they fingerprinted him, they took him to the County jail. That kid was very likely terrified. Taking his bike and driving him home would have been enough to get his attention. This was excessive to the point that he'll hate the police. Is that what you want? Had the officer exercised his responsibility to act with discretion and taken him home, there would be no problem with identifying him later. They printed him without parental permission. IMHO, that's a violation of parental rights when the parent is legally (and morally) responsible for the child AND his acquisition of a "motorcycle." And this brings up the real cause of this mess.
Ultimately, the problem is with the State of Florida. A bike capable of running on public roads as "a motorcycle" should be required to have all the equipment, title, license, etc. as any other motorcycle. Else, either the sale was illegal or they shouldn't claim it is one. Hence, the State is putting the regulation of buying a motor vehicle on an 11yo kid. Hell, they don't do that with cars, do they? In fact, they punishing this kid for an instance in which their lack of oversight is culpable. Get a grip.
