is it an offence to knock on some ones door and run?
No, it's not illegal, however, a boy was killed in florida few years ago for playing this game. The homeowner felt threatened and shot the boy who stumbled to a neighbors yard before he collapsed dead. It's really not worth the risk. Also, you could be charged with trespassing and/or vandalism in some cases.
It's not against the law, but some people consider it rude.
Don't worry too much about it, it's a common prank for giggles and junk.
I do believe you could be charged with trespassing since you had no intent to visit the person.
its fun... but the people might have called the police... but hopefully you'll be well away by then. X
I guess it could be seen as harassment (which is an offense...)
But that really would be pushing it...
it's well fun 4 da people doin it, an reeeaaally annoyin 4 every1 els
If you mean illegal, my guess is no. However, I'm not a lawyer.
no but they can call the cops and they'll get pertty mad
