How is this for the association of death in 3's?

On Saturday March 14th, Police found 9 bodies in Mexican Border. Imagine that it is a multiple of 3. State security stated that the total of nine bodies, which 7 were male and 2 females had been found. One was handcuffed however, all were tortured.
The police have arrested a suspected leader of a drug cartel hit squad for the 9 killings.
Honestly, what is this world coming to. Is no country safe? Do we not only have to watch what goes on in our own country but now have to worry about other countries as well? Aren't we already doing that.
Please voice any opinions - here's my take - if the US would stop getting involved in every ones (other countries) rivals, and mishaps, wouldn't we actually have a world where people would learn how to defend for themselves instead of having someone always bailing you out. Lets look overseas, why are the troops still there? How many cities have revamped their lives and are starting over and making their day to day activities normal again? So once again, why are they there? Protection? HA Comfort? HA -- Don't you think we are letting countries not rely on themselves for the devastation's that we ourselves are going through as well? No we bail them out, it's not called help, if anything it makes matters worse.
