That is obviously unacceptable. In my opinion, anything remotely related to firearms trafficking must continue to be subject to mandatory minimum sentences.
The gun dealer may not use the gun to cause irreparable harm, but that person will enable other organizations or individuals to do so. When criminals walk around with a gun, they still do it with an intention. These people do not carry or possess a firearm just for fun. They know that they might have to use it in certain situations. For example, they might use it against rival groups or against the police, as the police are trying to prevent illegal activities. This is obviously very serious.
In my opinion, and that of many of my colleagues, people who facilitate the acquisition of a firearm are obviously as guilty as those who use them, because they enable them to cause irreparable harm by giving them the opportunity to do so. We must never forget that, at the end of the day, a person who owns a firearm can injure or kill someone. When a firearm is used, there is no turning back.
