Any person which has been charged with a non-capital crime is generally entitled to bail. Different states have different laws, which apply to keep those accused of violent crimes in custody until their court hearing if they are deemed a flight risk or continual danger to the public.
Bailing someone out of jail who has a history of untrustworthy behavior can create headaches. You're essentially agreeing to put up 10 percent of a bail bond that could be tens of thousands — or even hundreds of thousands — of dollars. If they fail to show, then you went to all that extra trouble for nothing.
