That is to say, the younger those who have been arrested and imprisoned are at the first offense, the more likely is the possibility they will be repeat or serious offenders later. This is because on the inside not only are they able to learn even more "specialized" criminal techniques, after they get out, because they have been "labelled" as bad guys, it is difficult to go straight.
這是說，越年輕時曾經被捕入獄的人，將來成為累犯或重刑犯的機會越大，因為在裡面不但能學得更「專業」的犯罪技巧，出去後也常因被「標籤」為壞人後，難走回頭路。
