Loss of liberty is different from loss of job.

No trial necessary. Just enough evidence that the responsible person (boss, owner, board of directors) can make a decision.

The person holding the smoking gun would be placed in jail, freedom deprived, possibly without bail until the trial. If the BS resume person was suspended, no pay, no access to do any damage, while there income was freed up to pay someone to do their job, maybe an immeidate firing would be avoided. But due to the issues of employee turnover, training, long ramp up time for projects, institutional memory, etc, I'd say the company should not be burdened.
