I’m unclear about which particular actions the OP is talking about. Mostly, I see the BLM movement as leading protest marches and vigils and such. That seems very traditional to me.
One problem they have to deal with, though, is that unlike the Civil Rights Movement, this problem is NOT going to be solved at the national level. Each state, and possibly many cities, are going to have to be taken on individually. We might be able to create a national consensus that could work, in some cases, at the local level, but the government in Washington isn’t going to fix the problem of local police forces.
It’s a daunting task, and I’m afraid the attention of the nation is going to shift away from the issue except when there is some major news event that throws it back into the spotlight. And right now, the focus is on Islamic Terrorism again-- a real problem, for sure, but it shouldn’t even be in the top 5 that we’re worried about as a country.
