Two years after its maiden publication, the author felt the need to revise the book. The Congress, in a span of the same period, has enacted several special penal laws which are relevant in the study of law such as: Anti-Safe Spaces Act (RA No. 11313), Motorcycle Crime Prevention Act of 2019 (RA No. 11235), and Anti-Terrorism Law (RA No. 11479) – the latter law expressly repealing RA No. 9372 (Human Security Law), which was prominently featured in the 2019 edition of this book.
