Tens of thousands of people have been marching lately in Romania to protests the decriminalization of offences such as graft and abuse of power in public conduct, not to mention corruption. This would literally bring out a considerable number of prisoners, and it would also close the current investigations on a considerable number of politicians within the country, hence the uproar.
The revolt brought out tens of thousands of people in bitter cold, which will soon make it even bigger as the law was adopted late last night (at midnight), in secrecy.
The law will take effect in 10 days, until then it is up to the people to protest and for the Magistrates and Constitutional Court to take action.
A little info from Romania, since you might have noticed a considerable number of news lately about it.
