In the U.S. generally speaking, if you are found to be acting in self defense when you shoot another person, there generally is no punishment. You may, depending on the circumstances, have to hire an attorney, and there have been cases where people appeared to have acted in self defense but went to jail anyway, but there are usually mitigating circumstances, or some sort of odd law.
You will have to go to court.
It depends on local legislation.
Federal prison time, fine.
The same as if you were arrested for any crime. You would be tried to determine if you broke the law, and if you did, what the proper punishment would be. "Gun charges" is a very vague term- punishment would depend on the crime.
I know that a felon can NOT own a gun but is there any problem with a felon being around someone who has a gun?
Czech gun laws require gun licence and registration of proper firearms (made after 1890, not percusion, not airguns etc..). Gun licence is "shall issue" even for selfdefense. Schools are not gun-free zones. (sidenote: CR had more ccw licences per capita than Texas in 2009) Handguns and "evil assauls weapons" are legal for licence holders 18+ old or 21+ for self-defence. See wikipedia for more detailed information.
Up to and including death depending on the cirucumstances
Threatening someone with a gun is a serious crime that can result in various penalties, including imprisonment, fines, and a criminal record. The specific punishment can vary depending on the circumstances of the threat and the laws of the jurisdiction where the crime occurred.
only get time 4 agrresion only selfdefense and u dont get busted
5 Years!! Mandatory, Look on cps website
This is the same thing as say breaking a TV. If it is not yours, it could be considered vandalism. The highest punishment for this would be a fine and maybe a night in jail.
You need a lawyer
