Yeah but, with regard to silent-running, not only has your ship grassed you up to the five-oh when you
did the crime but when you're, as far as they know, an unidentified ship silent-running toward a bunch of SysDef ships, your ship must be transmitting a signal saying "Yo! Guys! It's him! It's the guy who did the crime. You don't need to verify his ID or scan him. Just light him up like a roman candle on bonfire night"
Seriously, it's not a big deal but you'd think it'd be fairly simple to make it work more plausibly, whereby if you do a crime out of visual range of cops they need to complete a scan on you before they all turn red and start shooting.
You'd still be Wanted (because you were reported by your target when you attacked them) but the cops wouldn't actually become hostile until they scanned you to verify the ship they're looking at IS the one involved in a crime.
