Always Be Vigilant

As events today in London demonstrate, we must never let down our guard. An attack may come in any public place. Our law enforcement must be proactive. They must not play catch and release with potential terrorists. The suspect must not merely have an ankle monitor as seems to be the case with today's attack. It is impossible to stop every lone wolf or copycat, but apparently today's assailant was already known to be radicalized. Today's terror never should have happened.
