(22,336 posts)and they wanted to get attention again. This is the one-year anniversary of Michael Brown's death. Sanders was speaking on this anniversary, and their earlier protest at one of his events was successful. They got tons of press. They want attention because nothing is changing and they're pissed off about it, and they're going to keep trying to get attention until something changes. Bernie's events appear to not have much security so they're able to protest there, and it is an effective way to get attention.
This is how protests work. They piss people off and get attention for their cause. They're getting attention. And yes, they're pissing people off. Protests are messy.
The people attending Bernie's event might have responded more kindly, because that would have reflected well on Bernie.
