First of all, police officers aren't members of the government (neither are soldier, civil servant). The police service is a state institution, yes, but it is made up of civilians.
Emniyet Genel Müdürlüğü is part of the state. They represent the state. Hence, they should apologize and provide reparations for racist activity.
Also how does them police officers top them being ultra-nationalists?
Stop making excuses for them.
There is no wider campaign of genocide against Kurds in Turkey, only claims from extremely biased sources which are related to PKK in some way. If you have any evidence to suggest otherwise, post it.
Yes there is. Check Wikipedia: The European Court of Human Rights has condemned Turkey for thousands of human rights abuses.[42][43] Many judgments are related to systematic executions of Kurdish civilians,[44] torturing,[45] forced displacements,[46] destroyed villages,[47][48][49] arbitrary arrests,[50] murdered and disappeared Kurdish journalists, activists and politicians.[51][52][53] The use of Kurdish language, dress, folklore, and names were banned in Kurdish-inhabited areas.[33] In an attempt to deny their existence, the Turkish government categorized Kurds as "Mountain Turks" until 1991.[33][34][35][36] The words "Kurds", "Kurdistan", or "Kurdish" were officially banned by the Turkish government.[37] Following the military coup of 1980, the Kurdish language was officially prohibited in public and private life.[38] Many who spoke, published, or sang in Kurdish were arrested and imprisoned.[39]
Sounds like the Turkish government was pretty hell-bent on eradicating Kurds and the Kurdish identity. That's the quintessential definition of genocide. Oh, I forgot. They did it to the Armenians too. In fact, the Turkish government has a long history of genocidal activity towards non-Turkish minorities. Excuse me if I'm not giving Turkey the benefit of the doubt here.
It is well known that İHD mostly exaggerates actions of the Turkish state and stays quiet about the crimes of the PKK. Adalet Ağaoğlu, one of its founders, even left the organization because of this. So, yes it is biased.
Ah yes, when you can't refute the claims, all you can say is "biased!" "biased!" By the way, the IHD is well respected across the world. Just not in Turkey where there's a huge clampdown on journalists and violations of human rights.
And the IHD wasn't the only one with the reports.
