here's my response - let's see if the moderator approves it.
The belief that there are people 'assigned to protect us' is sadly mistaken.
In 1856, the U.S. Supreme Court ruled that local law-enforcement had no duty to protect individuals, but only a general duty to enforce the laws. In 1982, the U.S. Court of Appeals held that "there is no Constitutional right to be protected by the state against criminals or madmen. The Constitution does not require Federal or State government to provide services, even so elementary a service as maintaining law and order."
As recently as 2005 the Supreme Court ruled that the police have no duty to protect an individual, even if that person has a restraining order against the person who did them harm! The police only have a duty to maintain public order. The case was Castle Rock v. Gonzales, No. 04-278.
The only person responsible for your safety is you. Firearms shift the balance of power for self protection because when seconds count - the police are minutes away.
