As far as police conduct goes, the Milwaukee PD operated excellently in the face of the surrounding chaos. Per Western Journalism:
“First, they extinguished the flames, giving rise to a lie spread by protesters that tear gas was being used against the crowd. The Milwaukee Police Department’s Facebook page cited Officers Joel Rossman, Jedidiah Thompson and Jutiki X for recovering the flag and giving it the honor it deserves.
After the flag was recovered, officers conducted a respectful, impromptu ceremony to properly and respectfully fold the flag, ignoring the protesters around them.
Police said the flag would be retained by the department ‘to be inventoried for possible charges against the protester.'”
The police's professional handling of the situation won plaudits from observers, as Western Journalism adds:
“‘Thank you to the police who did the right thing. And to the self centered, disrespectful protesters, I hope you realize just how horrible of an act you did. Our flag should always be respected and protected. I hope they press charges,' wrote Angela Miller Hoag.”
