I'd be dogshit.
Do you remember the night of the 17th? No it was too long ago.
I'd be worse at sorting out the composite drawing person. Fucked if I know how to describe features? Melancholy nose? I know they draw (!) stuff out of you but I doubt I could give them a starting point with my mum (!).
So if you want to murder someone I recommend doing it in front of me.
Ever been a witness? Ever murdered someone?
