The police in my city allege that a man committed some computer-related
crime. It could be child porn, some Internet related fraud, or something
else. The police arrested him, and held him for a bail hearing.
The trial won't happen for a year, maybe more. Unless there is some societal
interest in keeping him in jail before the court decides whether he is
guilty, the court will want to release him on certain conditions.
In this kind of case, it's likely that a family member will offer to monitor
the accused, as a condition of his bail. The family member will make sure
that the accused does not behave in the way that the police alleged that he
behaved before (eg. child porn, fraud, etc). The family member will revoke
the bail, if the accused breaks the rules.
The accused probably needs to use his computer for work and other legitimate
things. Although the police have charged the accused, he hasn't been found
guilty; the charges are just allegations. The family member's monitoring is
a compromise.
