(that you've encountered)
british - 6/10, lose points for no guns but unpredictability.
german - 8/10 - leather jackets, khaki/brown uniform, intimidating POLIZEI branding.
french - gendarmes 9/10 (technically part of the army not police, these guys do not give a shit)
french - police 2/10 (rubbish, they drive renault twingos ffs)
swiss 9.5/10 - just scary. look like something out of a dystopian sci-fi. http://image.shutterstock.com/display_pic_with_logo/154333/154333,1318857087,1/stock-photo-zurich-august-zurich-police-patrolling-the-streets-during-swiss-national-day-parade-on-august-86801509.jpg
think that's it.
on another note, how many different types of POlice does america have? too many. sheriffs, troopers, DEA, FBI, marshalls, 'boys in blue', highway patrol, loads more.
