I do not support this tact. Many states have had background checks and waiting periods, to no avail. Stop discrimination against law abiding citizens and start taking mental illness seriously. We must also accept that in a free society there will be homicide for reasons that are not preventable. Trying to prevent all homicides is ludicrous. People are very clever and unpredictable. Do not support additional background checks. This will make criminals out of otherwise productive and law abiding citizens.
