This is very similar to a phenomenon that's happened here in Egypt over the last year or so. There have been a number of videos of police brutality, filmed on cellphones by the police themselves, that have made their way onto the internets. This brave blogger (Arabic) in particular has posted many of them. The videos have included a man being sodomized with a stick, and a woman being tied upside down by her knees to a stick suspended between two chairs.
The authorities' response was naturally to deny everything and to say that the videos were faked, which they weren't. There has never been any serious effort to rein in the police, who operate with total impunity.
The man who was sodomized on video was later sentenced to three months in prison for "resisiting arrest."
It seems that the reason why the police videotaped the assaults was in order to further threaten and humiliate their victims -- they would threaten to distribute or show them to the victim's neighbors, friends and family, to shame the victim. This is an based culture, so that threat of public humiliation is a very effective one, especially in the case of a sexual assault.
After the outcry, we assume that the police are no longer videotaping their assaults, or at least not doing it so often. But nobody believes they're no longer assaulting people.
Anyway, here are the instructions for embedding video; there's a simple macro you can use.
Good luck in your fight against this police brutality.
I'm pretty sure that for a while, at least, the policemen will stop videotaping their assaults here too. However even if this time the police officers do get into serious trouble, I don't think that in the long term there can be any result unless there is a series of judicial decisions against violent police officers.

I hope the situation isn't that bad in Greece.
Whenever any human rights groups or foreign governments issue the slightest criticism of Egypt on this issue (or anything else, really) it results in a torrent of angry statements from various government officials about how nobody has the right to interfere in Egyptian internal affairs, sovereignty, etc. But since Greece is a member of the EU, it really is supposed to be meeting certain international standards for humane treatment of prisoners, and so hopefully the pressure to do so won't fall on such deaf ears.
One would expect that European nations would aspire to hold themselves to higher standards than Egypt....
