As it says in the article, it appears that the Costco employees (either through panic or in an effort to get faster police response) embellished their account of what Scott was doing in the store. If this led to cops thinking they were going into a confrontation with a wild-eyed armed nut, then Costco is certainly responsible. Then there's the conveniently malfunctioning surveillance equipment...
And... since the missing video might be proof of Costco's and the LVPD's guilt, it will nevermore exist. Had it provided proof they were not, it would have been on that night's news.
12 of 40 witnesses loosely agreed with the LVPD explanation that Scott reached for his waistband.
What did the other 28 say? Where is there 'statement'?
Is it in the same vault with the videocam footage, the zippered holster, and the Costco customer's cell/cam phones?
