Try them. Then fry them.
Maryland police Officer Jacai Colson
Well that would be nice but Maryland doesn't execute murderers. The death penalty is on the books but I believe it is "suspended" while a more than decades long "study" determines whether the death penalty is "needed", or something like that. In effect, there is no death penalty in Maryland and someone can commit murder in Maryland and never worry about any bodily harm being officially inflicted upon himself by the State of Maryland.
Nearly all of states are like this and Americans wonder why there are so many violent crimes being committed. No one fears any serious retribution from the law.
