Portia deRossi, T.R. Knight, Janet Jackson and others joing to film Lawrence King PSA

In the wake of the tragic murder of Lawrence King, the Gay, Lesbian & Straight Education Network (GLSEN) and LOGO (AfterELton.com's parent company) have enlisted the support of a number of celebrities to film a PSA urging people to "stop the hate" and ensure the safety of ALL students in our schools.

Participating in the public service announcement are T.R. Knight, Portia de Rossi, Janet Jackson and many others. Let's hope the loss of Lawrence leads to the prevention of this happening again.
