Very few "organized crime groups" scare me in that I just don't travel in their circle.
Sure, I could accidently pull out in front of a Hell's Angel or a member of the Bandido's and bring down a wrath. Or I could be a little too curious about the single wide mobile on the way to work that constantly has different vehicles in front of it.
But for the most part, I just don't encounter their ilk in what I do or where I live.
The Los Zetas don't care. If you are in the parking garage or at the stop light when they come in after a target, you are getting whacked too. They go from zero to full blown massacre in the matter of heartbeats.
And they are getting stronger and they are spreading out further North....
