reacting to a thief?

[mishink7]

If I saw a 4k bike, i would try to steal it too.

IF I had a 4k bike i would buy a 500 hundred dollar super-anti theft system for it that would beep frantically and send out a 1000000 volt whenever touched by someone who is not the owner. Not only will you catch the bad guy, but he will have permanent brain damage for the rest of his life. Good way to keep you, the bike, and society safe from villians.
