I agree with you in some respects, but resorting to force at this stage is a horrible idea. It will only give the police a justification for their actions and many people will side emotionally with the police, thinking the violent protestors deserved it. As it is now, most people side with the protestors.
The pigs don't need any justification for their violence. They simply beat and gas people whenever they feel like doing so. They also use violence at their whim across the country in contexts other than protests.
I'm not comfortable with the idea that people should simply allow themselves to be used as doormats and punching bags for the sake of sending a message. (If I or any of my loved ones were treated that way, I'd be much more than simply uncomfortable; I'd seek revenge, regardless of the cost to myself.)
Moreover, I'm not convinced that most people side with the protesters, though I admit to not having seen the relevant polls. I do know that most Americans suffer from Stockholm syndrome and have been conditioned to genuflect before any thug who wears a badge. Any police misconduct or brutality is dismissed by these people as "a few bad apples" when in fact the entire law enforcement community is rotten to the core. I doubt this mistakenly positive view of the police will change as long as the police limit their senseless brutality to a minority of the population.
Nevertheless, I'm not saying that it's necessarily time for the shooting to begin. As I said, if people want to avoid that, then IMO they need to find a way to hurt the system economically. Boycotts of businesses that deal with the police and others responsible for the growing police state would obviously be in order. No doubt there are other things that could be done, though I honestly haven't thought about it too much.
For example, imagine if the police didn't have tear gas and instead just shot protestors. The fallout from that would be enormous, and like the Boston Massacre, it would solidify the country's desire for real change. The worst thing the police could do would be to rachet up the violence, and I think they have already gone too far, out of fear. Overplayed their hand. The best thing for the protestors to do is keep at it and not back down or switch tactics.
No doubt police shootings of protesters would cross the line. If that happened and Americans didn't start killing cops in retaliation, then we would all deserve to be enslaved or shot for our cowardice. America's founders didn't win their freedom by allowing the British to use them for target practice.
What they're doing really does have the potential to change things. The police and the Feds agree, or else they wouldn't be so quick to violently repress when that kind of strategy is probably going to do more harm than good in the long run.
Sadly, I don't think it will change a thing. The pigs are violently repressing the protesters not because they fear them or their message, but simply because the type of asshole who's attracted to law enforcement these days finds it fun to beat up on "hippie scum" or anyone else they consider beneath themselves. It's nothing more than a bunch of sadists getting to indulge their fetish IMO.
I wish the protestors understood economics and monetary theory a little better, heh, but they really are patriots for getting out in the street like they are, and we should support them 100%.
I do support them just for making a stink, although in truth there are a lot of things I'd much rather see people protesting about (such as a surveillance state that's growing far out of hand).
