are different.
Signs in front of City Hall are going to be visible on security cameras.
Swanning about at your localbuni range with stolen property
is a good way to get jacked up when some fudd dimes you out.
"Stolen gun-free zone signs found at local gun club;
thief under arrest" is an easy headline.
You have to swipe them at night, ideally during a downpour,
leaving no identifying information on videotape,
and get rid of them ASAP.
