CNN:
Authorities have identified a Facebook post believed to have been made by the shooter around the time of the attack, according to a law enforcement official familiar with the ongoing investigation.
In it, the writer says: "I hope people call me insane... (laughing emojis).. wouldn't that just be a big ball of irony? Yeah.. I'm insane, but the only thing you people do after these shootings is 'hopes and prayers'.. or 'keep you in my thoughts'... every time... and wonder why these keep happening..."
Sounds to me, in my personal and utterly irrelevant opinion, like wanted to promote gun control?
While potentially informative, there’s a whole lot of missing content and context in that alleged FB post.
Then, someone had to leak it to the media. In the middle of an active investigation.
Just some things to consider.
