>>i'd say to aviod jail... getting a air rifle or paint ball gun.. hehe<<
Actually, it's rather too bad they do not make paintballs using that hard to remove UV dye that certain anti theft devices use.
One good splat with that, and they're easy to find since the dye will flouresce under UV light, and it's hard evidence to prove beyond doubt that they are your perp.
The problem with involving the cops in most towns, is that they will generally let the kid off with probation, IF they even bother with that, and they'll come back pissed and retaliate.
It's your call, of course, but my method of preference is a beatdown so brutal it will require an ER visit, because if they are in mortal fear of even going NEAR your moped, not only will you have to worry less about that specific punk, his friends will often hesitate to approach it as well.
As a lesson, a little spilled blood goes a long, long way.
Unfortunately, our society has made defending your person or property all but illegal, so if you choose that path, be fully aware of it's potential consequences, long and short term.
Work within Society.
Perp gets maybe probation/community service.
Very good chance they'll seek revenge.
No chance of you facing charges or scorn of others.
Work outside of Society.
Perp gets what they deserve.
Little chance they'll seek revenge.
Significant chance of facing charges yourself, and being considered by society as worse than the perp for the rest of your life.
In the end, it's your decision, however.
