All this complaining about anti gun activists. You guys realize something NEEDS to change right? What are your proposals?
The only change that would prevent this is to just... ban mankind. Face it, violence has existed since the beginning of time. It's just a reality of life. It fucking sucks but you can't legislate evil. Even if you could manage to find some way prevent the guns that were used (the black market would always provide a supply), what's to prevent the guy from hauling ass into the crowd with a box truck full of explosives and leaving a crater in the stadium that kills thousands? Look at the bombings in Paris and Manchester for recent events. The Oklahoma City bombing killed 3x as many as this Vegas shooting and was done with basic items you can purchase at your local Tractor supply. Evil will always find a way.
If someone is hell bent on slaughtering dozens of people, why would they give a shit about a measly class D felony gun charge?
EDIT: Events like this give an illusion of a major issue with guns but it's really not. Despite these mass shootings, your chances of getting killed by a gun are still extremely low. Last I checked, there's around 33,600 gun deaths each year in the US on average. That's 10.6 per 100,000 people or about .0001%. Of these deaths, the vast majority (around 65%) are suicides that are no threat to anyone but the person committing the act and is something that's going to happen anyway. Another 15% are by officers in the line of duty or in self-defense cases. About 17% are due to criminal activity, gang violence, murders, mass shootings, etc... acts that actually are a threat to the public. The last 3% is due to accidental discharge. So the 17% or about 5,100 deaths annually by guns in criminal acts is a more realistic number. Even more realistically, many of those 5,100 are one-on-one personal matters in drug deals gone bad, criminals taking out other criminals, etc... but lets roll with the 5,100 number for now. That 5,100 is just 1.8 out of 100,000 or .00000.... *calc error* ... fuck it, it's really really insignificant is the point.
You know what you are more likely to be killed by in the US? Let's make a list, shall we...
Heart disease - 633,800 deaths annually (124x more likely)
Cancer - 595,000 deaths annually (116x more likely)
Chronic respiratory diseases - 155,000 deaths annually (30x more likely)
Accidents in general (all included unintentional falls, wrecks, etc...) - 146,500 deaths annually (28x more likely)
Stroke - 140,300 deaths annually (27x more likely)
Influenza - 57,000 deaths annually (11x more likely)
Drug overdoses - 41,000 deaths annually (8x more likely, includes alcohol related)
Motor vehicle accidents - 34,000 deaths annually (7% more likely)
...gun deaths that are actually a threat to innocent people are way way down the list. Yet, look at that list above. Heart disease and cancer from such as obesity and smoking are perfectly legal. Alcohol kills way more people every year and yet it's legal. The left wants to end the drug war and legalize all drugs even though they kill more people every year than all gun related deaths put together. Hell, you're 7x more likely to die on your way to work tomorrow morning than you are to get killed by a gun.
Going back to the 5,100 number, 29% of those occur in the big 4 crime cities of Chicago, Baltimore, Washington DC, and Detroit. What do all of those cities have in common? Really strict gun control laws. It's proof that gun control legislation does not work. All it did was disarm people who had no intent of ever committing a crime or turned everyday non-criminal citizens into criminals with the stroke of a pen. The criminals certainly don't care about legislation, especially when they have half the city PD on their payroll.
When you really stop to think about the issue at hand and think about it logically, you can see the big picture. When you make uninformed knee-jerk emotional reactions like gun control legislation, you end up with piss poor legislation that solves nothing except to disarm innocent people who never committed a crime.
