“The Davis Police department has been hitting me with ultra sonic (sic) waves meant to keep dogs from barking,” the letter said. “I notified the press, internal affairs, and even the FBI about it. I am highly sensitive to its affect (sic) on my inner ear. I did my best to appease them, but they have continued for years and I can’t live this way anymore.”

The handwritten note was signed “Citizen Kevin Limbaugh.” Also recovered as evidence from the man’s home were two unregistered guns.

“It’s not just bad social policy. It’s incredibly bad politics,” said GOP consultant Mike Madrid, who has been vociferously imploring his party to renounce Trumpism and expand its electorate. He was among a group of former California Republican Party political directors who signed a recent letter urging the rejection of “messages of hatred, division and rhetoric that divides us by race.”

Vietnamese-Americans, Madrid said, represent “the only ethnic diversity in the party to speak of.”

Days after losing her re-election bid in deep red Utah, Representative Mia Love, the only black Republican woman in Congress, condemned President Trump on Monday in a scathing concession speech, describing him as having “no real relationships, just convenient transactions.”

Radar is a powerful military tool because it makes it possible to spot enemy aircraft beyond the line of sight. It does this by sending out a burst of radio energy, which bounces back when it encounters another object. So-called “stealth” aircraft try to get around this by becoming invisible to radar — either by using flat, angular shapes to reflect radar signals away from radar equipment or by using materials which absorb radar signals.
