Its the phrase "All but one were lucky enough not to kill someone and have it caught on film that went to a lefty media outlet."
The implication is that every single police officer on duty at that protest hit a protester with enough force to kill albeit someone with pre-existing medical conditions. That's every single officer - presumably including those who made the complaints against Harwood. I've yet to see any evidence of this and frankly struggle to understand how Merrick can claim to know the actions of every single officer that day - omniscient or what?!?
Without this evidence the statement as I said earlier is 'flimsy' at best?
