1) I don't see how that info HAS ANY BEARING on this case.
3) *THEY approved the erection of an ELECTRIC/electrified fence.....
5) The police had been tracking/following the woman for a week before they arrested her. (Stalking is usually done with malicious intent, if the police did indeed have malicious intent you could say it I suppose. Stalking is more often used to talk about criminals/perpetrators.)
