Yes, there is. Just look which has happened and this thread is about.
If carry a gun everywhere you can kill anybody with the excuse of the "autodefense".
Even in the case of Martin attacked him, do you think its reasonable to use the lethal force for an unarmed boy?
Here my opinion, and just my opinion so don't start then here flaming me: if the vigilante had been black and the boy who shoot white, he would have already been tried and convicted...
I think there's something wrong with the gun control laws in the USA.
I think you're wrong. You obvsiously aren't from here so you don't have a great understanding so let me help. If you want a gun you can not go into a walmart and pick one up and walk out with it along with your groceries, there is a waiting period and series of checks required. You can not carry a gun around freely without a permit (except for Texans), if a police officer stops you it flags that you have a permit. There are a variety of restricted weapons unavailable to us hillbilly rednecks as your cartoon depicts (by the way you'll find the lowest incidence of gun violence within the country rural folks of America)
Carrying a gun does not give you the free pass to kill whoever you want in self-defense. That's a wild claim that is backed only by your own personal belief. The people who are going to kill others are going to do so with or without the law being in place. The ONLY reason this is a big deal is because of the stand your ground law which exists in some states and muddys the waters a bit, is it good in theory? Absolutely, in practice perhaps not so much as is beginning to be seen. However that will not stop justice in the form of a court trial if pushed to a federal court.
The neighborhood watch is NOT armed, you don't sign up and get issued a weapon. The weapon he had was his own, and that is fine. Self-defense is perfectly legal and justified when defending yourself from an unprovoked attacker, lethal or not. The question here is was it unprovoked and therefore justiified? Did Treyvon go on the offensive? That should be the question, and you can not deduct that solely from the 911 tapes and a couple of very old pictures.
You're statement that if he had been a white kid this would be a whole different story is so far beyond the point its ludicrous. And no he wouldn't have been tried and convicted already, it would probably be playing out just the same if not less. When a crime is committed against a minority in this country more support groups, alliances and coaltions rise up to support the minority free of charge than you could imagine, if anything being black may just get you the better court defense.
By the way 17 year old American kids aren't all the law abiding innocent kids the media makes them out to be. The youth in our country (generalization but not far off) is getting out of control in terms of respect for others, elders, law and law enforcement. They aren't scared of cops, they aren't afraid to break laws, there is subculture that enjoys acting like thugs and gangsters (which this Treyvon was a part of *reference his twitter account @No_Limit_NIGGA,) which you wont be familiar with unless you're here to see it progress and get worse every day.
I am not saying that being in that thug culture means you deserve to die, but it does open our eyes to a more clear picture of what could have been seen that night. Also take into consideration that the pictures used of both individuals were not accurate in that Treyvon was a big guy (6 foot 3) who purposely appeared to be a thug due to the subculture he enjoyed being a part of, not the little middleschool kid that is being posted all over the internet. Zimmermen was not this big heavyset guy, that picture is from a previous incident and you can see in the released video his is a pretty slender and average to a little short. Point being don't believe everything you see in the news, and don't assume innocence until all the evidence is gathered and displayed in court.
I am not defending one side or the other, I am simply saying you can not make an educated decision on evidence that is altered, distorted, perveted or twisted by the media to make a good sob story, you need to wait for the facts. You can claim this is racial, sure, (in my opinion the people who go straight for the race card are more racist than those who don't.) You can say our gun control laws are to blame, but who's to say it wouldn't have happened without them?
I'm really getting tired of older teenagers being portrayed as innocent little kids, I suppose the 15 old girls who savagely gang up and brutally beat another girl are innocent of their actions, or the 15 year olds who form a mob and beat two police officers down to the ground requiring the fire department to go in and rescue them don't know right from wrong. Back in the day maybe, but times are changing in our culture and it needs to be recognized and addressed.
Like I said, dont rush to judgements without the facts, people die everyday and they don't get this much media attention. When it gets to the point where Skittles has to issue a press statement, the press has gone to far.
