Removing guns will not remove the problem, they will find another way.
While a total ban on guns in never going to happen, there needs to be change.
These mass shootings are becoming more frequent and doesn't seem to be any effective measures put in place to prevent them.
Agree, even if guns are banned officially there`s always black market that doesn`t care about laws. In case a killer lacks a gun, he can easily use a knife (although with much less "efficiency"), or even make a home brew bomb - there really is no reliable way to 100% prevent such events.
Something should be done apart from banning - it seems the easiest solution, but it feels like the government wants to ban and forget about the problem instead of actually taking actions to fix it.
