Answer:
True
Explanation:
An unstable person is a reckless person. He can do anything to anybody or can commit any crime at any place without thinking of its outcome or the consequences.
An unstable person shows different signs such as he acts suspicious, he may feel nervous and may seems lost, moves here and there suspiciously, etc.
Thus by knowing and following the person's activities we can identify the potential harm that the person can cause to others. Knowing the indicators of the person's activity and behavior, a potential threat that the person can cause can be identified and can be prevented.
Thus the answer is true.
