Outside apprehension also eliminates unpleasant scenes which might disrupt normal store operation. You may prefer to apprehend a shoplifter inside the store, if the merchandise involved is of considerable value or if you feel that the thief may be able to elude you outside the store premises. In either case, avoid verbal accusation of the suspect. In general, this is all the more reason, if your evidence is sufficient, to call the police and proceed with prosecution. Failure to prosecute first offenders encourages them to try it again.
Some organizations have control files on shoplifters who have been caught.
Your retail merchants' association can inform you about the services available in your area. You can check these files to see whether the person you catch has a prior record. Naturally, each situation must be handled differently and your good judgement is required. You may wish to release elderly or senile shoplifters and not press charges where there's some indication that the person could honestly have forgotten to pay for the merchandise. In most cases, however, prosecution is in order.
