Motoring offences, juvenile misdemeanours, gruesome murders, child abuse, terrorism, white-collar fraud, regulatory breaches – London’s crime sets handle just about every kind of violation you might imagine. Check on the orientation and reputation of the sets you are hoping to apply to, and look at the biographies of juniors and seniors. You may spot an emphasis on defence or a focus on a particular type of crime. Some, for example, specialise in terrorism and extradition; others are boosting their regulatory practices, perhaps in specific sectors such as sport, professional discipline or health and safety. Pupillage involves a baptism of fire, early advocacy and court visits across the capital and beyond. Those motivated primarily by money should look elsewhere.
