Among the country's principal human rights problems were xenophobic and racist incidents, including both hate speech and hate crimes involving violence, and cases of anti-Semitism. Local nongovernmental organizations (NGOs) noted that police investigations of cases involving anti-Semitic and xenophobic acts often did not lead to the apprehension of perpetrators and that some prosecutors declined to pursue cases of hate crimes and hate speech. An increasing backlog of cases and lengthy court procedures, which impeded the delivery of justice, continued to be a human rights problem. Criminal defamation laws restricted freedom of speech and press by discouraging speech, publications, and material on the internet critical of public officials.Other human rights problems included mistreatment of detainees at time of arrest and during questioning, abuse of prisoners by guards, compulsory hormone therapy to lower sex drive for some convicted sex offenders, and at times inadequate cell space and exercise space in detention centers. Sometimes there were restrictions on prisoners' contacts with family and other persons outside the prison. Delays in the restitution of private property continued. Official corruption remained a problem, despite enforcement efforts. Burdensome procedures discouraged appropriate classification and treatment of domestic violence as a crime. Societal problems included discrimination against women in the labor market, abuse and sexual exploitation of children, trafficking in persons, and discrimination and violence against ethnic minorities as well as lesbian, gay, bisexual, transgender, and intersex (LGBTI) persons. Violations of workers' rights to organize and join unions and to strike as well as antiunion discrimination also occurred. The government did not always effectively enforce laws governing the work of minors between ages 16 and 18.The government generally enforced human rights and took steps to prosecute officials who committed abuses, whether in the security services or elsewhere in government.
