OP, glad you're OK, mate. Better to lose some cash (painful as it is) then suffer serious injury or worse. Hopefully, the police will prioritise your case, since it involved a firearm. With a bit of luck, the robbing pricks will be too stupid to break their routine (especially if this just the first one that has been reported by a punter). Maybe the police can trace her IP address or even question her to find out the identities of the robbers? Or they might even trap them with a dummy booking (if they can be arsed ofc).
Just to reassure anyone nervous of contacting the police: they don't judge you or take the piss, they tend to be very business-like and want as much info as you can give them. Your family won't find out unless you have to go to court and give evidence - and that's only if they trawl through the court listings (who does that?). I had to speak with them and was soon put at ease.
Stay safe guys. And good luck, OP.
