We already have backround checks. When people who aren't eligible to buy guns, try to buy them, which is illegal and punishable under fed law to up to 10 years, they are not prosecuted. 72,000 tried to buy gun, who also lied on the fed form only 42 were prosecuted. Face it Obama wants more laws but is unwilling to enforce the laws we have. Joe Biden says the government doesn't have the time to enforce those, so why should we pass more laws they won't enforce.
