Although mass shootings often hurt everyone and are blamed on guns, they have not really affected the public's views and attitudes on this issue. The above survey data may tell us why there are so many large-scale gun cases, but there is no progress in dealing with this problem.

Although Americans say they don't want their legitimate rights and interests to be violated, they still support some small and specific gun control laws. For example, we should check the identity and background of gun sellers more carefully and stop selling semi-automatic weapons and offensive weapons. This does not conflict with Americans' demand for the protection of gun rights. Similarly, they say they don't like health care reform, but they like specific new health care laws. They prefer concrete and feasible things to shouting slogans and listening to political views.

There are three levels of American police: federal, state, city and county. The federal police and the state police exercise the police powers entrusted by the federal and state respectively. The police power below the state level is decided by the state itself. Except for the federal police, state police, city police, county police and private security guards are not subordinate to the federal government, but directly led by local governments.
