This is Maryland we're talking about. (I'm sorry to say, my home state)
Maryland may be predominantly democrat, but we certainly don't produce a Massachussetts or California brand of liberalism. In fact the state is mostly conservative if you cancel out Baltimore City and PG County. In every such instance I can recall (including the ones provided in the article)no home or business owner has been prosecuted in the state for killing and intruder in self defense. I am not saying that it has never happened, but I cannot remember it happening. I also note that every firearm that is legal in the United States is also legal in Maryland.
