When Lisa said to Brody "What are these, indigestion tablets" I thought, that's exactly what they look like. Either that or a tin of mints. But the bit I found hard to believe was that anyone would use such a large tin to carry five tablets. Surely they would be supplied in blister packs.
I do wish TV would stop showing women putting fit young men in arm locks so easily, even a strong man has difficulty doing this, if the victim resists. I know that a woman who is a highly trained martial artist probably can do this, but I do not think that Lisa is that highly trained. The average police officer receives minimal training unless they take it on them selves to seek in in their own time.
