From Jacob Sullum @ Reason's Hit & Run Blog:

On Tuesday the city council of Helena—West Helena, Arkansas, unanimously gave police the authority to impose a 24-hour curfew on any part of the city. A.P. reports that a 24-hour curfew already has been in effect in one especially crime-ridden neighborhood of the town for a week. (Doesn't that make it a 168-hour curfew?) So far the curfew has resulted in 32 arrests, mostly for misdemeanors. Although police, who are armed with "military-style M-16 or M-4 rifles, some equipped with laser sights" as well as "short-barrel shotguns," could arrest people simply for leaving their homes
