generally you did good....

but you blame as you say a "female PCSO" (i.e. not a full police officer but just a special) for just following the standard advise for the 'average' person - many would think they could deal with a nutter then fail badly and then they have 2 issues to deal with!

Your story had: a stupid violent driver; a stupid pedestrian; dumb on lookers.... but you choose  to call this a bad "Experience With the Police" - ?

Your attitude at the time = win
Your attitude in this post = fail
