Malicious Behavior

What do you do when someone you know (weather you choose to or not) is getting away with threatening you? When they are just malicious. We have been under verbal attack. But we really are worried that they could get worse. Should be hide, protect ourselves, call in the reserves? (The police will not file reports because we have not been threaten with specific harm or directly.) In all truth this person has already shot himself, what will keep him sane enough not to hurt someone else-----like ME!

I was thinking we might need to go out and get tactical gear. Like maybe something to protect our body (armored vest sound good to me) or head gear (riot shields) or maybe...Malice Clips! That is it. Sounds perfect. Something to control his malice. Wikipedia says Malice is a legal term referring to a party's intention to do injury to another party. Malice is either expressed or implied. Malice is implied when no considerable provocation appears. Well heck let's just clip that. But sad to say not the right Malice Clips. Nope these attach to vest to hold pouches. But that does take me back to a bullet proof vest!
