Actually, it is best not to even post beware of dog signs, or to advertise you have a "pit bull."
"No Trespassing" are the best signs to have, for legal purposes.
Beware of Dog signs are best for those...without dogs!
In court, prosecutors will use the fact you knowingly had a dangerous dog, and were advertising it. You knew it would bite.
And seriously, if a robber is killed by a dog,his family will try and sue! Even after a homeowner is found innocent.
Just like the idiots who warn intruders they have a gun on the property. It shows they are declaring they will shoot anyone, and want to.
Those signs are only good for the movies.
And quite frankly, warning signs actually make it more dangerous for the owner.
True criminals do not fear those threats, but they do prepare better and will most definitely use lethal force if they do invade.
Other than that, home security signs are quite effective. If you post a sign that your house is secured by a legitimate home security system, it is very effective.
True criminals know the good ones.
Brinks Home Security is one example. Brinks Home Security | Push-Pull-Rotate Knobs and Levers | Home
The truth is, there are unseen forces in the government trying to disarm Americans.
And the prosecution is flooding with their puppets these days, as the rights of Americans are stripped away...
