The political violence by state did not stopped. The secret service was still looking for enemies, arresting people or threatening their families. Not just physically, but also by forcing you to relocate, preventing education of your children or moving you into worst job possible. Just because violence and threat was not as high as during monster processes, it does not mean it did not existed.

You really really don't need tanks for that. An ordinary police is just enough. You really don't need willpower and determination to arrest people nor to confiscate their properties. You just ... do it. Easily.

Yet also, it is not like people and society would recover from repression instantly and forgot what happened a year later. The people stay traumatized and scared.
