Nobody drew more consistent negative attention in Cleveland than the group of Westboro-esque extreme evangelists with their fire-and-brimstone-for-the-homos routine. Utilizing their strength in numbers, police simply cordoned off any two groups that squared off in potential conflict, often with quick-reacting platoons swooping in on bicycles, dismounting and using them as barriers.
I saw at least one spotter (or sniper) on a parking garage rooftop; perhaps they helped coordinate from their vantage, as sometimes harried police hustled from one potential flashpoint to another.
More often than not police outnumbered protesters on both sides, often comically so. Sometimes you’d see a contingent around a lone character surrounded by opponents; for the life of me I couldn’t tell why this one in particular was seized upon.
