Things that make you go "hmmmmmm..."

[Undertoad]

If the President does something illegal,

and the Secret Service is part of the Executive Branch that administers law,

but is charged with protecting the President at all times,

...do they arrest the President... for his own safety?

If not, then protecting the President regardless of the law is their job, and the Secret Service should be buying the President's weed anonymously, and testing it for purity and potency.
