If the police felt especially threatened he might be shot in the leg or tasered (depending on what the police in that country is equipped with).
All the charges together would probably result in a hefty fine, something like a few thousand euros and probably some jail time (a few months tops).
p.s.: I'm talking about northern european countries here, southern/eastern countries are significantly less easy going.
If some gun was fired or if they are pursuing known serious criminals they use guns. In europe use of a gun is a planned action, not instincive response to feeling somewhat threatened.
Of course these situations are extremely rare as Western Europe is not as a violent society as the US is.
edit: to add: private citizens carying tasers ( let alone guns ) around is unheard of / extremely rare.
edit: this was in reply to 'if you are, you are living in fantasy land'. which OP edited away. lame.

But more importantly, the Dutch police will shoot to kill in self-defense, which is exactly the same as the US.
It also doesn't help that we leave our mentally-ill citizens to fend for themselves on the street, instead of giving them the care they need like most other first-world countries do.
Put the two together, and American police are faced with the very real possibility of facing an armed crazy person any day they report for work.
Most important training the police gets is how to diffuse a situation not how to shoot to kill.
