I do not believe your statement is correct.
Literally the first search I did was "police Poland" in a DDG news search on DDG and the third link was to earlier this month https://www.out.com/news/2020/8/10/polands-stonewall-police-... titled "Poland's Stonewall: Police Attack and Arrest Queer Protestors" :
> Nearly 50 people were arrested following the arrest of trans activist Malgorzata Szutowicz, better known as Margot, on Friday. The protests come amidst a rise in homophobic hate and rhetoric, and the recent re-election of President Duda who called LGBTQ+ rights a foreign ideology that seeks to destroy basic Polish values.
Or from https://euobserver.com/justice/149112 :
> Police were also investigating a separate case, in which a man on a balcony, next to a rainbow flag, grabbed his crotch during a World War II memorial march last weekend, Marczak said earlier. ...
> "No democratic country should allow the kind of incidents we saw, in which police enters people's private homes," [Rafał Trzaskowski] added, referring to police efforts to stop the balcony protester last weekend.
A DDG news search for "racism in Bulgaria" (literally my second search) includes this summary at https://www.bbc.co.uk/news/world-europe-50060759 about repeated racism by Bulgian football fans. https://www.theguardian.com/world/2019/oct/20/bulgaria-sofia... points out "While racist abuse of players inside stadiums attracts attention outside Bulgaria, within the country it is the Roma who are the principal targets of thugs in black and men in suits."
A DDG news seach for "black lives matter Croatia" finds https://balkaninsight.com/2020/06/10/balkan-protesters-show-... where we read "Activists in Zagreb, Belgrade, Podgorica, Warsaw and Sofia rallied to show solidarity but also to point out the problem of racism and police violence in their own countries. ... Dozens of people took part in a protest march in the Montenegrin capital Podgorica on Monday evening. “There is no doubt that racists are also hiding among all our local Balkan fascists.“"
