Dayton killer's gun was legally purchased inside the US, just like the guns of Gilroy and El Paso killers.
Some El Paso victims did come through the southern border, but probably didn't bring any illegal guns or drugs.
It wouldnt matter either way.
It's obvious these obsessed mass murderers will find away to obtain a weapon whether legally or illegally on the streets which are easily obtainable since illegally obtained weapons are used to commit far more violent firearm homicides, and injuries.
Many murderers have turned out to be ex felons. Did it prevent them from obtaining one illegally? Absolutely not.
Anyone hellbent on doing mass murder or murder of anyone will find weapons to carry them out just like they always do.
Just like the guy in an Ohio mall stabbed 10 before a legally armed citizen stopped him in his tracks.
Guns on the streets are cheap, and easily purchased by those who know they cant obtain one legally.
Although those with criminal intent all they have to do is pay a straw man or woman without a criminal background history to purchase the weapon legally for them.
There is no way to stop anyone from getting a weapon if that is their intent to get one. Far more mass shootings have involved handguns rather than long guns.
In the inner cities which results in thousands being shot every year are shot with illegally obtained handguns.
But sadly no one seems to care as much about illegally obtained weapons which are killing many thousands each year... with thousands more injured with one.
I wish people obsessed as much about getting the millions of illegal firearms off the streets, and out of communities as they do about changing gun control laws for over 150 million law abiding gunowners. Especially when the overwhelming vast majority of them never harm a soul, and have actually saved many lives including saving police officers who were caught in a crossfire with criminals.
