What were non transportable offences for convicts?

Non-transportable offences for convicts in the context of British penal transportation typically included serious crimes such as murder, rape, and armed robbery. These offences were deemed too severe for transportation to penal colonies, as the convicts would often face harsher punishment or execution instead. The rationale behind this distinction was the belief that such individuals posed a greater risk to society, even in a penal setting. Thus, convicts guilty of non-transportable offences were often sentenced to longer prison terms or execution rather than being sent abroad.
