about £60,000 a year within 3 years of graduation
The above is not necessarily true. In the UK criminal law is funded via the legal aid system, which means lawyers are often paid a reduced fee, which consequently impacts on salaries. Even in London a criminal lawyer may never make £60,000 a year unless they become an equity partner or unless they are doing a substantial amount of out of hours duty work representing detained persons in a police station to subsidise their basic salary. A more likely figure is £35k-£40k 3 years after qualifying.
In the US, a criminal defense lawyer can expect to start off earning $35-45K as a public defender, or slightly more with a firm. Depending on their experience and history, a seasoned (15-20 yrs) criminal defense attorney can earn anywhere from $60-200K, depending on where he/she works.
