The father of a Virginia journalist killed in an on-air shooting said Thursday he would become a crusader for gun control, but analysts said there was little likelihood of legislation on the federal level any time soon, despite changes in some states.

Two journalists, reporter Alison Parker and cameraman Adam Ward of Roanoke CBS affiliate WDBJ7, were shot during a live interview on Wednesday by a disgruntled former station employee who later killed himself. The woman who was being interviewed was wounded and hospitalized.

Parker's father, Andy Parker, urged state and federal lawmakers to take action on gun control, especially to keep firearms out of the hands of people who were mentally unstable.
