I agree the number that actually want that is now quite low, now that things have calmed down. I meant that maybe 15% of the entirety would be moved by such rhetoric at a convention, now.
One interesting thing to come out of the whole discussion, I will concede, is the most effective means of police presence. Those of us who are law-abiding typically envision that as simply a uniformed officer or marked car patrolling where we live. We figure (correctly) that it gives the criminals pause to hang around there, and they opt for easier targets, far away.
But within certain communities that police presence is viewed, not as a deterrent but more so as an antagonizing action. Not everyone in such a community will agree -- many will welcome their presence. But there is a perception amongst some that it represents harassment. We need to deal with that perception. Even if we think that is wrong (and I think it is wrong) it is subjective and folks in those neighborhoods need to be convinced the police are there to prevent crime in the first place, not just react. Its a long term issue.
