Dismissal and sarcasm are usually signs the arguer has run out of an actual argument.

My point stands, adding more gun laws to the gun laws already in place - you make an error in assuming there are no gun laws in place - will do nothing but let some people play pretend.

The root causes of violence are several, some are related to mental illness, some related to a gross lack of virtue (temperance, patience, fortitude), some are related to a growing detachment and an indifference to others that others have allowed themselves to acquire, not seeing souls, but mere bodies!  Some are related to true possession, people who have "given themselves over" to evil. 

The lack of "more and better and reasonable gun laws" are not influential in the problem or the fix.
