Consider this: Chief Heather Fong (left), is the first SFPD female, lesbian chief of police. Theresa Sparks (center), a former male, is president of the San Francisco Police Commission, CEO of a multi-million dollar sex toy retailer, and a transgender woman. Sgt.

Any questions?

THOMAS SOWELL RETURNS TO TOWNHALL to write on education at a crossroads: Part I and Part II. Read both.

TWIN STUDY: Astronauts suffer mysterious mutations in their DNA after spending just a year in space.

GRASSROOTS RAGE and the Democrats’ crackup. Except that it's not grassroots; it's astroturf. Bought and paid for by our 'ruling elite'.

CAN SELF-DRIVING CARS solve the bicycle problem? If running them over is a solution, then yes. If not, then my guess is probably not.

Read the comments; that's where the action is.

SCIENTISTS AT THE JAPAN AEROSPACE EXPLORATION AGENCY (JAXA) are testing an electrodynamic 'tether' - created with the help of a fishing net company - to slow and eventually de-orbit space junk.
