Your best answer will be to call your local PD, tell them the situation, and ask what your rights are involving detaining the suspects.
As I am not a lawyer or a LEO, this is purely a guess, but I think you could be getting yourself into hot water since you are a) not in any physical danger and b) are threatening kids (you never said how old, it would be worse the younger they are) with deadly force over property damage. Here in NC the use of deadly force to defend property is a no-no. Aside from any legal implications, I would think in this "Nobody's responsible for their own actions, sue-happy society" we live in now, some ambulance chaser would also love to slap you with a civil suit for false imprisonment and of course, the pain and anguish you caused these model citizens. If you can, take a picture, get the best description you can, and call the cops. They may be able to nab the little SOB's while they are still riding their BMX bikes home.
I pretty much already knew what the implications are, I was just venting. I posted this morning about an hour after the incedent. My neighbors called me at about 2 this morning, and said that the police was here. My neighbors, along with about 5 or 6 others on my street had thier windows shot out as well. Needless to say, I'm highly pissed off, and using your reply (and I highly appreciate your input as a logical, level-headed, law abiding citizen) in my defense, I'm not responsible for my actions (lol).
The legal implications are huge and bad, at least in my state. Yes, I'm a trial lawyer with criminal defense experience (15 years).
Generally, in my state, a citizen cannot use or threaten deadly force in protection of property. If you were to confront with a firearm a juvenile delinquent (or an adult) who shot out your car windows with a pellet gun, you likely would have committed a felony.
To me the only time to brandish any kind of weapon is if it is a life threatening situation whether there will be criminal punishment or not. Windows can be replaced a person cannot. I would definantly confront them if i cought them but not with any weapon.
Hopefully the little SOB’s still had the pellet gun in there hand when you caught them. If so (wink wink) you can say you thought it was a real handgun and only pulled your gun on them in self defense. I’m not a lawyer or a LOE but that’s what I’d use in my defense.
And that kills this thread. Thanks all for playing. And remember, if your post makes gun owners look like paranoid morons just looking for an excuse or justifiable way to pull their gun on someone, or worse, shoot someone, don't post it!
