Laws are not much of a deterrent. Those who have chosen to commit specific acts will do so regardless of the law. At best the law only impacts a criminal when the crime is committed and he is charged for the crime. The laws impact is not real heavy on the front end in comparison to the beck end. An example: The speed limit in one part of town is 35 MPH. That's the law. It does not keep those who decide to speed from speeding. When caught doing 45 mph in the 35 mph zone the impact of the law is felt. The impact is felt through a fine, time off work to deal with the ticket, and increased insurance rates. Whether or not that stops the person from speeding again is really subjective as it depends on the individual. The law only matters for those who have respect for the law in the first place. Concerning guns and school shootings we see the same principal played out. Adam Lanza broke 41 laws ranging from stealing the guns to murder. This was done in a state that has severe gun restrictions. The laws did not matter to Adam Lanza. Since he committed suicide he is not even available to be charged with his crimes. So, the laws became completely impotent in protecting people and in holding the criminal accountable for his actions. Adding more laws will only add to the charges available to be brought against someone who has no regard for the laws anyways. And too often these criminals even escape the charges.
