Mexican drug war

soo... it has come to my attention that this past week, and specially yesterday the Mexican government captured several heads of the infamous drug cartel "ARELLANO-FELIX" which is great... or is it? well dont get me wrong, im all against drug dealing and just drugs themselves, but i overthink things way too much, and im thinking... well, currently theres a pretty violent drug war between the Arellano-Felix cartel and the Cartel De Sinaloa, and just themselves they make quite a mess, now.. if the government keeps capturing the leaders of the mentioned criminal organizations then what are we left with?? let me put this another way, say... some country took obama, joe biden, robert gates, clinton, the eleven supreme court justice members, majority leader of the senate harry reid, and all other leaders of the country(hopefully they take sara palin), it would just be us without anyone to follow, and look at us! we dont even like each other, i guess what im trying to say is that if all the drug cartel leaders get arrested as fast as they are being arrested currently we'll end up with a bunch of confused, dangerous, mentally unstable, and highly armed delinquents that will eventually make smaller groups and most likely fight each other for territory. do we really want that to happen? if you asked me i applaud the action taken by the Mexican law enforcement agencies respectively, i had been asking for so long to deploy the troops to the streets and patrol the cities that have been hit the hardest by these organisations and just go all out, but in the end blood would end up running too. we have to start doing acting on this, or this will get out of control, only us trully have the power to bring them down. are we really that desperate, are we so weak we need substances to take control of our lives? supply and demand people, supply and demand
