All that is necessary for evil to triumph is for good men to do nothing. If there are no consequences to evil actions, would not more of those actions occur with progressively greater ferocity?

Incivility, disrespect, assault, and profaning a holy place are not concepts requiring advanced degrees in ethics to know they are unacceptable in a civilized society. In essence, this is not a “Catholic” issue. Common sense, common courtesy and common decency are universal concepts not limited by time, borders or the belief in God.

Personality and background play a major role in how each of us individually would respond in these kinds of uncomfortable/stressful situations. Most would be frozen and would watch choosing not to get involved except, perhaps, to call for help. Very, very few would intervene in a moment of crisis when possible injury to oneself might occur. We call those few, bold, self-sacrificing people “Heroes.”

Don't worry, Rope.
If I witnessed someone beating the pulp out of you, I would, most likely :-), intervene on your behalf and would give my cellphone to ACL and ask him to call the police.
