Wow dang. They were pretty close to the vehicle. Even distance twice as far as that could be deadly. Usually they get sprayed from way farther distance but wherever that was they rolled up way too close. I'd put blame on cops for that one heck you can see the vehicle still going forward practically feet away from them.
Yeah but then I guess the issue is that if a water cannon can be deadly if used improperly then we're in a similar situation as the current one where these tools have ways in which they are meant to be used (rubber bullets bounced off the ground) and police are misusing them.
