Sure. Jail is highly criminogenic. You spend a day in jail and you're going come out worse off than the day before you went in. You're going to become “hardened”, to use a word that may not fit everybody.
Anybody who spend six months in jail without bail is not going to commit a crime for those six months, but they're going to come out of it more dangerous than they were when they went in. As a result of that, as an overall society, we don't measure public safety only for the six-month period in time when one person is jailed for a set of charges. When that person's experience or journey through the criminal justice system ends, somebody else's begins.
Overall, if we talk about public safety and protecting lives, we will save more lives by giving more people community-based release plans than by incarcerating them and making them more dangerous to begin with...than any gains we realized from keeping that person behind bars for six months.
