DiFi may be disingenuous, but she is right this time. An M4 would have been much better. I really do not think that LEO were carrying AR15s. If the cops & military carry M4s, that is what I want. All I am asking is one, just one more stop on the saftey switch. Safe-Semi-Auto. One little notch further.
IIRC the m-4 has 3-round burst, not empty the magazine rock and roll.
