According to San Diego 6, Lansdowne said that it may take a generation but guns will eventually be taken off the streets through new laws like Senator Dianne Feinstein’s proposed assault weapons ban:

“Chief Lansdowne, who plays an active role in the western region of the International Association of Chiefs of Police (IACP) association, said it may take a generation but guns will eventually be taken off the streets through new laws like Senator Diane Feinstein’s proposed assault weapons ban legislation. Some of the items his organization is addressing include; a ban on assault weapons, restricting high-capacity magazines, closing loopholes that allow firearm sales between private owners without background checks, and implementing much stricter background checks by using a comprehensive database.”
