Lock the crazies up. Drugs are not enough.
They prescribe them drugs which sometimes they take. And sometimes they mix with recreational drugs. Or sometimes they don’t even take them.
And they may be at home but they aren’t under house arrest.
They still order things and buy things and train. Unsupervised.
If they aren’t legally accountable for their actions then they need a legal guardian with them at all times.
They “pass” for normal until they have an episode or several.
And the families of some of these shooters even report them to the authorities who then file papers and do nothing.
Many are known wolves.
