We have to defend all 7 directions, NSEW, above and below, and the subject himself, which means know the signs of radiation or chemicals; thus the pink light on Trump's hair. Pathways are another thing to check especially with chemicals, booby traps, or nefarious activities. Pathway attack are thwarted by having SS transgress those pathways before the President. Having a bunch of SS with him is a strong point but that does not resolve the weak points. If you get rid of all your weak points you are only left with strong points. Learn Kung Fu. Amen?
