Disclaimer pt.2: You may get away with it "in Texas, at night, and on your own property," but you have to hit all 3/3 of those, if you have 0/3, 1/3, or 2/3, you are also going to be prosecuted.
I remember there was some guy who installed spyware on a phone that couldn't be wiped off by normal means. Stuff that gave him remote camera access, location, file access, everything. Then he got that phone stolen and made a documentary about this dude's life.
I think it was baked into the OS somehow (probably what you said). He disabled system updates as well so the OS didn't wipe. The only way it could have been removed was flashing the OS, but you'd have to find out it was there to begin with.
Seriously, it's just mugging. The bicycle part is a whole separate issue, if you do this you're just mugging people. Same crime, same potential legal consequences, same potential for getting a sharpened screwdriver in your kidney.
While I dont necessarily agree, I do agree that petty theft affects regular people all the damn time, you cant do anything about it or you can catch an assault charge, the cops cant or wont do anything about it either so you just have to accept that sometimes people are going to take your shit and nothing is going to happen.
It would be nice to know those people get their comeuppance from time to time.
nah bike thieves are among the lowest of the low, among child abusers and oil execs. Utter sociopathy. It's one of the scummiest things you can do, hands down.
