When you have hundreds of people involved from dozens of law enforcement agencies, it takes a while to sort out the facts.
Meanwhile, the public is screaming for live streaming information about what is going on. 24 hour news channels have way too much time to fill. The police submit to the pressure and put out what they "know" before actually concluding an investigation.
This is obviously going to lead to conflicting bits of information being put out.
But I think we all know that if the police maintained silence until all the facts could be gathered, the same public would be screaming "COVER-UP!!!!"
The problem is that our country is overwhelmed with weak-minded people who manufacture shit in their heads in the absence of information. Then they are stupid enough to believe their own fantasies, and when real facts finally arrive, and those facts contradict what they made up in their heads, they scream "CONSPIRACY!!!!"
**** 'em. People like that who drink the demagogues' piss deserve to be lied to by their masters.
