On December 15, 2014, a gunman took hostages in downtown Sydney, Australia, leading to three deaths and four injuries. At 10:01 p.m. on July 7, 2016, a bombing took place on the 1258 local train of Taiwan Railway, leading to 25 injuries. Both of these cases received high international attention, caused severe casualties, and were categorized as cases of lone wolf crimes or lone wolf terrorism that were quickly solved by the police forces of Australia and Taiwan. A comparison between the measures of the police forces in the two countries can provide future references for other police forces when preventing, responding to, and investigating similar cases.
