During an event organized by the Popular Party focused on security, Sanz asserted that Martín is dedicated to "harassing, insulting, and offending" the regional president, Isabel Díaz Ayuso, and the mayor, José Luis Martínez-Almeida, instead of fulfilling his actual responsibilities. The Deputy Mayor emphasized that security competencies belong to the State, as established by the Constitution, and questioned the delegate's inaction.

Despite acknowledging Madrid as a safe city, Sanz warned of "serious risks" that demand responsible attention. She specifically criticized the delegate's stance on squatting, which she claimed downplays its real impact on affected families. She also condemned the management of drug trafficking, citing the dismantling of units in the Strait of Gibraltar as an example of neglect.

The Deputy Mayor also questioned the 'only yes means yes' law and policies on gender violence, arguing that they generate greater insecurity. In contrast to her criticisms of the central Government, Sanz defended municipal management, highlighting the recruitment of 2,800 new positions for the Municipal Police since 2019, bringing the force to 6,000 officers. She also noted the increase in the security budget, from over 300 to more than 500 million euros.

Finally, Sanz praised the incorporation of new resources such as tasers, drones, and metal-detecting gloves. She called for legal reforms to toughen the response to crime and advocated for a change in the central Government, expressing her support for Alberto Núñez Feijóo as the next president.
