John Oliver - Civil Forfeiture

Well, i come across with this John Oliver show, about some Police civil forfeiture procidements and i don´t know what to thinck about it.
USA, the country that advertisse freedom and it´s considered one of the most liberal and people are confronted with some of this civil forfeiture laws....i sincerly dont know what to thinck.

How can this be possible....HOW?
Civil forfeiture !!!!
I leave the comments up to you because, i´m sure you´re (US citizens) better informed about how is it possible...cause i can´t understand it.
Can someone explain me how can this laws be passed.....really?
