Obviously all blokes with beards can't be suspect but I'm on my guard when I meet someone sporting a growth !!
Blimey, well you're on dodgy ground hanging around this forum Tigler.
When you say 'beard combined with a moustache', do you mean a la 'The Master' from Dr Who (in the old days). In which case, your feelings are understandable. TV could do that to people in the 60s.
