Earlier quoted context omitted.
Philadelphia instituted a youth curfew because local highschool kids developed a interest in flash mobs. Not flash mobs where lots of people in a train station start dancing all of a sudden, but rather flash mobs where they all start texting all of their friends that they are going to all meet at 15th and South Street in 10 minutes to riot and loot. I'll grant that in most cases youth curfews are probably senseless,…
If it were adults, would you be as casual about people being told to stay in their homes because of some troublemakers?
A curfew was implemented during the 1992 LA riots and enforced by the California Army National Guard. I think that is the sort of situation which you are describing, and I think that a curfew is appropriate in that sort of situation.
Would I be casual about it? Casual is a weird word; nothing about that sort of situation is casual. I would support such a curfew however.
