Police departments have expressed concerns about the Hello Kitty guns and other guns painted to look like
toys. They have said that the only purpose of modifying guns in this way is to conceal them from police officers by disguising them as toys, thus giving the advantage to the gun user. They also pose a danger to children, experts say, as they may mistake the real guns for toys and inflict harm on themselves or others. Users of the guns say they are not criminals and it is a matter of personal expression. Pink guns are popular among wives of law enforcement officers.
