My view on the whole blocking the highway thing still stands, but making it lethal to kill protesters does make a lot of room for that law being abused, I feel like excessive force should be allowed in the context of say those Antifa activists, they were blocking a road for, forget I'm not sure why even.
This law is bad, but the context behind it I can agree with, and thinking about it this law is pretty unnecessary, police can already use lethal force, but if this law comes about then it would mean that almost any protest, peaceful or violent, would be subject to it.
