Not sure if revenge, retribution, retaliation or Tabloid Tales of Horror is the way to go here. Hatpins? Swords? Good grief! Fact is, most of us (and I'm sure Diane too until this unfortunate incident) can happily go through life without meeting violence / violent crime in any shape or form outside of dramas on TV - or the endless sensationalism in the papers - much less the murky savage realms of The Brothers Grimm - or the bloodier realms of Traditional Folksong & Ballad if it comes to that. It is, in any case, EXCEPTIONAL and people are, for the most part, GOOD.

The important thing here is that one is open enough to more effective channels of personal healing & empowerment than feeling it necessary to tool oneself up or else let one terrible incident define ones life thereafter.

This seems like a good place to start : GOV.UK : Get support as a victim of crime

Hope you can bounce back triumphant, Diane - with your essential self-respect, dignity & humanity in tact, and with no need of weapons to feel safe on familiar streets. Sadly, shit happens; happily, this is often just the beginning of a STORY which will lead to a Happy Ever After.
