An Associated Press-Ipsos poll after the Virginia Tech shootings showed Americans are still divided on the issue. Forty-seven percent said firearm controls should be tightened, 38 percent said they should remain unchanged, and 11 percent said they should be loosened - about the same as in a January survey. A Zogby-MSN interactive poll showed most did not believe stricter gun control policies would help prevent massacres like last week's.
