Which of the following actions is classified as a Class A misdemeanor under the Texas Private Security Act?

Impersonating a commissioned security officer is classified as a Class A misdemeanor under the Texas Private Security Act because it poses serious risks to public safety and undermines the integrity of the security profession. This action can lead to significant legal consequences, reflecting the state's commitment to regulating the private security industry rigorously. The law aims to prevent individuals from misrepresenting themselves as professionals who are afforded certain powers and responsibilities, thus protecting both the public and the legitimate security personnel.

The severity of this designation as a Class A misdemeanor also stems from the potential for harm that can arise when an unauthorized individual assumes the authority of a security officer. Such impersonation can lead to abuses of power, breaches of trust, and increased danger to the public.

In contrast, other actions like failing to return a registration upon notification or violating a provision without a specified penalty, while still important, do not carry the same level of immediacy or risk to safety as impersonation. Attempting to perform security functions without registration is indeed a cause for concern but typically carries different legal ramifications compared to the serious nature of impersonating a commissioned officer.
