https://reason.com/blog/2019/02/08/houston-cop-involved-in-deadly-drug-raid Reason has entered the fray, sort of taking the cops side but calling the liars too.
The "wrong house" theory took a serious blow when it turned out that at least some of the officers who had participated in the raid also had participated in the investigation that led to it, meaning they surely would have noticed if they were 12 miles from where they were supposed to be. The description and address in the warrant affidavit make it clear that no such screwup occurred. But it is obvious from the outcome that other kinds of screwups did occur, possibly coupled with deliberate dishonesty.
my personal opinion is, it was the wrong house - the cops who took part in the controlled buy were probably just taking the word of their informant
and somehow whomever it was couldn't pronounce or spell or otherwise communicate the difference betwixt "hardy" and "harding".
"participated in the investigation" probably equals "talking about the case over donuts and coffee at a donut shop"
My brother is a lead detective in a multi jurisdictional drug enforcement task force, a perk is having a nice breakfast at a nice diner on newyorkers dime and time - where they discuss ongoing investigations and plans for the day.
I'm willing to bet these guys in HPD had their informant make a buy, and someone misunderstood the address but the cops had already filed the paperwork that they had been at the address already.
probably had done the same thing a bunch of times with nothing going wrong.
of course, i could be wrong
