Trying to make sure I understand your Q and "inside" info definitions.
When you say "inside" knowledge, you include info from persons
'inside' the home, whether as a resident, FT or PT employee; cleaners; aupair; tutor, coach,etc for kids; lawn service; plumber; electrician; exterminator; gen contractor who did permit-work 2013-14; building-permit inspector; gas co. rep; decorator; window washers; painters; massage therapist; physical therapist; home health care; art appraiser, ins agent; caterers & florists for parties; alarm co; carpet installers; floor refinishers; home-theater installers; party guests, neighbor-visitors, club members; friends of kids;
whether in prior week, month, or anytime since ~2002 home purchase
anybody who has legit reason to be in home or on premises, IOW,
did any of these ^ppl^ provide any info directly to DDW (or to DDW's chums) who then sparked idea for these crimes?
If they ^ provided info to DDW and did nothing else, does that count as assistance?
To clarify, does surveillance by DDW (or chums) count as "inside" info?
What about ppl who work for or with ^ ppl, but do not come to home, such as billing/bookkeeping for above entities.
