The video was made by PPetermann80, and shows him as he shot and destroyed 60 Gallente Police, before safely warping out of the system. Here's the story in his own words.
The System is Bille (0.6) (Region is Everyshore if I'm not totaly wrong) the gate is the Elarel gate. After losing another ship to Gallentean police forces I decided to take revenge. Fielding an passive drake with f.o.f. missiles I jumped to highsec and killed 60 police ships (cruiser & battleship sized) before I ran out of ammo and jumped back to low sec.Pretty neat stuff if you ask me. Didn't think it could be done. But there you have it. Enjoy the video - and if you're looking for the high-quality version here's the link on EVE-Files.
