3 days ago, I dreamt there was a big #POLICERAID in our neighborhood. At 5am, IT HAPPENED! Cop cars all over, troops in combat gear. Several loud #BOOM s! #MEGAPHONE : "THIS IS THE #FBI ! WE HAVE A WARRANT! WE HAVE YOU SURROUNDED! COME OUT WITH YOUR HANDS UP!" This went on for about a half-hour.

The world's first electric #megaphone was invented in Japan in 1954 by TOA Corporation.
