C, Now and then are probably going to be different. The people you buy milk from are not going to turn into criminals, no one is saying that. However for example; (many years ago) a guy came to where I work one day that knows the owner of the company. Starts a fist fight for fun then looks at me and says “he’s planning on hitting me in the head with one of those pipes” He was right.
A few days later he was interrupted in a breaking and entry by the home owner. In the scuffle the perp bites the end of the guys nose off and swollows it. Days later it takes 10 cops to subdue him and 3 are hospitalized. People like this will take over what every they can find, a store or gas station or the power plant. These are the people you better have a mind set to deal with in some manner.
