Do you have faith in the legal system and do you feel that law enforcement officers do enough?

Vigilantes are regularly romanticized in books, comics, movies & TV. From Batman to Dexter, these characters are often portrayed as heroes or idols.

Without dwelling too much on superheroes with superpowers, do you believe there is a place in society today for a person or group to take the law into their own hands to make the streets a safer place?

Or are such people nothing more than power trippers and thugs trying to justify a life of violence? Is it too often used as a mask for acts of terrorism?

These groups operate across the world and include freedom fighters such as the IRA (or as least the old IRA were), the Sea Shepherd Conservation Society (active against whaling and fishing vessels), and many more underground groups.

Would you feel safer if the number of vigilante groups/people increased?
