Do you intervene?

So…do you intervene?

A hidden-camera experiment by the ManKind Initiative claims that onlookers in public react in strikingly different ways depending on the aggressor’s gender, The Mirror reported.

In the first case, filmed in a London park, a male actor attacks his “girlfriend” in front of shocked witnesses — and they get involved very quickly.

There’s a threat to call police, and another witness adds: ”You don’t have to put up with that honey, he’s not worth it.”
