Since I keep getting challenged on this lets try some numbers.

This is from 2011/12 and apparently mostly from CSEW survey. I can find more stats if people wish but this is a busy time of year for all of us. BobbyBingoo will immediately pick up on the front page that men are indeed very much more likely to be victims and will jump around for joy.
You can then turn to the bottom of page 19 where it states that 86% of offenders are male. Now you can quibble about my descriptive terms of 'nearly always' if you like but for me that does mean men are more of a problem in violent crime than women (and, again imo, that women have every right to be a bit pissed off about that).
What really bothers me time and time again, bringing us back a little closer to the topic, that no one in power really seems to think that this is important. It is not listed as one of the key facts on the front page, you have to read through the whole report and find it buried at the bottom of the page and never referred to again.
Why is the fact that men are more vulnerable to violence a key fact, but the fact that men perpetrate most violence not? Do you think the nature of the offenders would be considered more important if they were, eg female, black or islamic, 'cos I do.
You can't address a problem without understanding its causes: that's why these reports are produced. So why is this key fact never really addressed?
2 reasons, imo: 1) no one really knows what to do about it; 2) no one wants to do anything about it, i.e. they don't care. For most people as long as they are not affected they don't care about anything or anyone else.
