Not for simply being on your property, no. A certain set of conditions have to exist before the use of lethal force is authorised. Lethal force may not be used to defend yourself if you were the one who provoked the confrontation. It may not be used to defend against simple assault. There must be an imminent threat of death, maiming injury, or rape. You also have a duty to retreat from a situation of using lethal force if possible to do so. I don't know if Maryland has a castle law or not, but, even if they do, it only removes your duty to retreat when you're actually inside your home or personal vehicle - it doesn't apply to the property outside of your home.
You can only legally shoot someone in Texas if they are on your property and doing something that breaks the law.
No
only if you are a mass-hole
Technically, no, you cannot shoot someone for trespassing. You can shoot them if they break and enter your house. You can shoot them to prevent them from committing a felony. But not for trespass.
Laws are complicated, which is why we have lawyers. So yes, you can use a legally owned handgun to prevent a crime in progress, even if you do not have a license to carry a concealed weapon. However, if you shoot someone, or kill someone, you may still be accused of having used excessive or unnecessary force. Even if you do not shoot anyone, but you do discharge the gun and damage some property as a result, the owner of that property may sue you. So I won't tell you that this is entirely free of risk.
As long as you shoot it on your property at your property.
Yes
Yes, if you only shoot your property.
If you only shoot your property, on your property you will be fine.
If you shoot on your property at your property you will be fine.
You are not responsible for what others do with their own property, unless you knew they were a felon.
