There is no such thing as an absolute fix for crime, I doubt anyone could reasonably expect one, apart from locking everyone up.
Getting noticed in itself will help reduce crime levels.
On a different point - a couple of years ago we had a group of around a dozen offenders working on the (very overgrown with brambles) nature reserve alongside our garden, all in high-vis vests. I have never seen any before. They all looked very sorry for themselves, working for weeks clearing 3 acres of thick bramble and entirely pointless, it's as thick again.
