You gun experts educate me. There were rumors of him using a "flash suppressor". Does this mask the flash that one of those guns would have? If so, how well?
Considering that, the swat did a very good job IMO. Just wondered how hard it would have been to see those flashes.
Oh yeah, one other question. My understanding is guns like those would create a lot of smoke. Therefore wouldn't the fire alarm have went on in that room pretty quick and then that info would be sent to front desk who would pass that on to cops? If one room has a smoke alarm going off, I'd expect that one should be checked as a priority. (I know easier said than done, but something I have pondered.)
