The political class can afford the expensive guns and private bodyguards. The poor cannot. The poor are NOT more violent than anyone else. They are easier targets. In the case of senior citizens, taking away their right to own and carry a firearm turns their right to self defense into and empty concept.
Seniors lack the strength and agility to defend themselves with other tools, or to flee attack.
Unarmed they are easy prey for thugs. Middle class and poor seniors are most at risk. They are living on fixed incomes that do not stretch far enough to pay for private armed body guards. They do not have large amounts of money to contribute to politicians, so they are denied the privilege of a permit to own and carry a firearm. They are reduced to being targets for the thugs and the punks looking for an easy target.
