Your video is old.
"They have to have proof if they're charging the boyfriend. well see in the investigation."
(those charges were dropped)
"if (the cops) are wrong, someone will get fired."
(one of those three cops has been fired...so by his own admission, they were wrong. i'm saying...that's not enough)
"if they issued a no knock warrant, that needed strong proof to justify that."
(there are now reports that there was false info in the warrant requests, and that 5 warrants were approved in under 12 minutes...not exactly an exhaustive process for approval, and oh yeah, the judge that made that approval has been reassigned since this case)
That video contains a lot of speculation that has been proven otherwise at this point, and at every turn his conjecture gives the benefit of the doubt to the police. This is problematic in cases where police might have done something wrong. Be very careful about who you give the benefit of the doubt.
