Good to hear no one got hurt. this sort of thing really pushes my buttons and the sad thing is if you hurt or injure these scum bags in any way they can sue you!
also, u are lucky no one has poisoned the dogs because I have seen that many times as well. thieves are the lowest scum on earth. catch them in the act and brutalise them for a few hours just for the fun of it.lol
My father in law used to work security. He had a couple of Dobermans and still to this day often talks fondly of one of them in particular. It saved his ass on many occasions, but unfortunately someone poisoned it. Even if a guard dog were to bite one of these losers you could be liable for damages. What a joke. That's one thing we could certainly learn from the USA - You should have more rights than a criminal, but here were too soft.
Gotta love our Judicial system, NOT!
