Turns out criminals don’t telegraph to family, friends, and the public when they are about to go shoot someone.
It seems to be some kind of odd finding for this author, that criminals don’t typically telegraph to the world THEY are violent criminals!
The exceptions to this rule are the mob, mafia, and other government-funded-alphabet-letter-agency-backed groups!! These groups of people talk about their rabid want and need to maim and murder people by volume! And the reason these groups tell everyone is they know 99.9% of the people within these groups will not cooperate with the police when push comes to shove!!
Other criminals have to seem like they have a somewhat normal life to keep the shade off their criminal careers!!
