Should there be stricter weapon laws

Should there be stricter weapon laws? In the past months there have been an increase in assaults, shootings, and other incidents involving ‘assault weapons’ or ‘military style weapons’. Many times in different situations we tend to blame the objects used, but is it really the fault of an object or rather the person? In shootings people blame the gun, but in car accidents do they blame car? Why not ?
People say that the weapons used in these tragedies are considered to be ‘military style weapons’ when in reality pistols are used vastly across the U.S. military as their sidearms; shouldn’t they take action against that too as it is technically a military style weapon. Humans have a tendency to want to blame something or someone when something happens.
