You mean this:

The New Black Panther Party and two of its members, Minister King Samir Shabazz and Jerry Jackson, were charged with voter intimidation for their conduct outside a polling station in Philadelphia.

Two members of the New Black Panther party, Minister King Samir Shabazz, and Jerry Jackson, stood in front of the entrance to the polling station in uniforms that have been described as military or paramilitary.[3][4][5] Minister King Shabazz carried a billy club, and is reported to have pointed it at voters while both men shouted racial slurs, including phrases such as "white devil" and "you're about to be ruled by the black man, cracker."[

So they were standing in front of the entrance, wearing military garb, pointing weapons at people and screaming racial slurs.

Now compare that to what happened here:

“There is a gentleman standing outside the office with a holstered gun,” Brown told HuffPost. “According to law enforcement, because Virginia is open carry, he’s allowed to have it.”

Brown noted that the man was “being nice” to people, and that he appeared to respecting the observed 40-foot no-canvassing zone outside of the entrance.

This guy wasn't pointing a weapon at anyone, he wasn't wearing militant clothes, he wasn't blocking off entrances and he wasn't screaming racial slurs.

This woman claimed he said "Who you gonna vote for, Crooked Hillary?", which is about as unintimidating of a sentence as can be. Nowhere was he threatening her in any way with violence.
