Search Results: get her without risk

Yesterday a guy threat my life because of his girlfriend, this slut added me on Facebook, liked all my stuff and when I tried talking to her on the chat, she ignored me, so I went to her profile and said I was going to delete her from my friends, this dude came and talked to me in the chat saying he was her bf, and he was going to kill me, the Good thing in this is that it happened on the web, so there was no risk whatsoever. But look, a random psychopath woman adds you and frames you, so she can feel like the all hot good for nothing mentally sick girl, while her boyfriend kills another other guy just because he was jealous, imagine if it were in real life, I probably would have been shot, I can fight BJJ and Muay Thai, but I don't have a gun and it's impossible to use one in this fu**ing country (Brazil) without getting arrested, even if you have one legally.
Soon afterwards, a girl that I met two weeks ago and had a crush for me told me her boyfriend is arrested, so I got like "What the hell are you talking about? You never told me you had a boyfriend, and it's even a thug, you know what, get lost from my life.". What the hell is going on with these women? I know women rather men who can offer them protection, but that's ridiculous, and getting killed in Brazil is as simple as taking a cup of water, once the law only benefits rich people and bandits. There's another thing, imagine me with my friends in a night club, we meet some girls and go out with them, the other day one of us is dead, he got killed by an ex, or something, and the police won't do nothing about it. I'm seriously considerating moving to USA, should I do that already? Which of these places of the poll have laws that works properly?
