Dogs, outside dogs. Preferably Border Collies as they are super smart, high energy, and love to be outside and will defend their land and bark their heads off at strangers (which is usually the best defense) which would also alert you to a strangers presence.

No guns and no violence man (unless of course they come in your house). The electric fence deal does sound great though, with warning signs of course.

It very well may have been the cops that got your crop, could have seen it from overhead in the ghetto bird. When this happens they land, chop, fly. You could also move your grow INDOORS. Better luck next time. :hippy:
