I suppose folk have to weigh up the pro's and con's before stepping into a potentially violent situation (sometimes just the threat of ringing the police is enough).
As far as your companion is concerned,was he right to say don't step in?
I think if you can help one person who's being attacked or abused its a small victory and being quite isn't the answer (I know, it cost me a tooth).
A lot of violence however, doesn't happen on the street it happens (at home) behind closed doors.
Perhaps like violence, my grammar is a crime and I should just be quite
