Texas isn’t always as big as it thinks it is, but when it comes to penology, criminology and things forensic, Texas really is B-I-G – it was the first state, for instance, to start shackling its convicted felons with electronic balls and chain so that they could go stir crazy at home, and it also houses a Center for Forensic Studies at Texas Technical University: latest brainchild of the tecchies there is a laser scanning system that enables fingerprints to be detected on soft surfaces such as cloth, and even flesh, adding another golden rule to mother’s facts of life for their daughters – men who wear gloves are up to no good.
