The mass shooter in MD (occurred in Edgewood at his place of work), was on parole for 12 felony convictions, served 12 years and was paroled, was not an ideal prisoner. After he was paroled, he was caught with a loaded gun in a traffic stop, gun sitting on front seat in plain sight. The Cecil County State's attorney declined to press charges. Since a convicted felon cannot possess a gun, this was go straight back to jail, do not collect $200. He eventually murdered 3 or 4 people and severely wounded another 3 or 4 people.
Yesterday in Prince George's County Maryland, a off duty cop went to help a neighbor in a domestic dispute, the husband killed the cop. The husband had several outstanding warrants for domestic violence going back 8 years. Somehow the warrants were never served and he remained on the streets.
The left likes to talk about doing something to stop the violence, yet somehow they refuse to lock the violent people up and keep them there. How many gun crimes are plea bargained down to lesser charges. Too many straw purchases are never prosecuted.
Look at Nikolas Cruz, numerous teachers and students at the school immediately guessed he was the school shooter without being told. This guy could have only been more obvious he wanted to shoot up a school if he wore a sandwich board stating that. Local LE visited the Cruz house 39 times about him, Social Services interviewed him and did nothing when he admitted to cutting himself and stating a desire to buy a gun. The school system did not refer him to LE for his numerous issues. The FBI ignored two complaints about him and his desire to shoot up a school, never even bothered to pass the information on to local LE. All it would have taken to stop him was a conviction on misdemeanor domestic violence or requiring a mandatory mental health examination and he could not have purchased a legal firearm.
Look at the Texas church shooter. the Air Force never notified the FBI that he was dishonorably discharged which would have prevented a legal fire arm purchase. He was also required to take a mandatory mental health exam (preventing a legal firearm purchase) and this information was not add to the background check system.
The current laws and systems will stop most of these lunatics if the laws are enforced and the required information that could block firearm purchase is actually added to the system.
