President Trump:

I think as security precaution that the White House should have bullet proof glass going all along the inside of the fence, at the height of the fence. Keep it 6 inches behind to make it easier to power wash from time to time, keeping it clear, where it will not take away from the aesthetics. This would make line of site targeting impossible, and give the necessary time windows for any other type of assault that may occur due to this obstacle. ThankQ for your attention to this matter.
