No system of background checks would have prevented the Dallas shooter from getting the gun he used. The Media is simply spreading propaganda to achieve the goals of the left wing of the country. Increased background checks are not the answer as it doesn't solve intent.

The one thing statistics cannot answer is how many deaths have occurred because somebody couldn't get a gun. For example, gun control advocates love to say that there were X number of suicides by guns last year. We should remove those guns and those people would be alive. What it can't tell you is how many of those suicides would have happened by jumping off a bridge, or overdose or ??? The problem with suicide is it is the intent of the person to kill themselves. The gun is simply the tool used. 

The same holds true with mass shootings. Remove the guns, and now it is mass bombings because the intent to do harm is still there. Removing the guns fixes a symptom, not the problem.
