SA-7, suuuuure...! Man, what a lie.
That makes me wonder if he really does even have a Barrett.
I think not.
While I sincerely doubt he has any type of MANPAD, I do think it's worth recalling that back in September 2011, NYPD Chief Kelly was interviewed on 60 Minutes, and made a cryptic comment referring to the NYPD's ability to shoot down an airplane. This raised some eyebrows, and in the days following the interview, both Kelly and Bloomberg backtracked saying that they had a .50 sniper rifle they could fire from a helicopter and that was what Kelly was talking about. Needless to say, the explanation met with a lot of skepticism.
My point is, again, while I truly doubt Dorner has any type of SAM, the notion that a police officer in the NYPD or LAPD could get their hands on one may not be as far-fetched as it may at first seem...
