I have all that saved word. doc; 2005, 2006,illegal immigration marked a significant change. Huge increase too, AK-47's on the street, coincided w/ for example, Los Zetas killed Dallas Officer Mark Nix I believe it was. That would be your time period and the variable one would control for is illegal immigration,i.e. "dreamers" porous borders, meth, meth and more meth, heroin, etc. cheese, handcuffed meant nothing all of a sudden.
