It would be good to have all the facts before "seeing it for what it is". I have seen a lot of conclusions of which have little or no regard for those who have been injured or killed in this insane killing spree. 

A little insight: There were over eight weapons reported to have been in the shooters possession. One thing is for sure, this was an extremely calculated massacre. First reports indicate that a fully automatic AK riffle was the weapon used in the assault. No fully automatic weapons are legally sold to regular weapon buyers.

There are 100 round magazines available for AK riffles. However, at full auto, firing more than a few hundred rounds, full auto, through an AK would destroy the barrel. "Technically", fully automatic AKs, "plural", could fire  900 rounds in 30 seconds.

A single shooter in Vegas? 8 plus weapons tells me probably more than one shooter. My understanding is the shots were blind shots into a tent. 50 dead and over 500 injured? Let's wait and see the reports.
