Here is what I think (I know I will be burned at the steak for this):
The media market is the constant.
Media organizations and reporters are incentivized to get the most extreme and sensationalistic footage, so they are taking more risks and crossing more lines than every before.
I've not seen any footage that reflects that - and there is plenty of footage of police attacks on reporters at this point.
Reporters know that these attacks are happening - it's their job to know what's going on! They don't want to be attacked, so they aren't taking risks.
