At various times those imprisoned have included human rights defenders, journalists like Mikhail Trepashkin, and scientists such as Valentin Danilov. Since 2007, loosely-worded laws against "extremism" or "terrorism" have been used to incarcerate the often youthful activists who have protested in support of freedom of assembly, against the alleged mass falsification of elections in 2011 and, since 2014, against the occupation of Crimea, the conflict in eastern Ukraine and corruption in the highest echelons of the government and State. Political prisoners are often subjected to torture in prisons and penal colonies.
