Some time in the 20th or 21st century, in a country with a high degree of street crime some employees of the local police force decide to establish a party, the PPP (Party of Patriotic Policemen)
It is a center-right, generally Conservative party whose core ideologies also include adherence to Secularism and some degree of egalitarianism, while strongly advocating change towards a stronger rule of law and harsh measures towards decreasing violent crime. The party also proudly incorporates Cop Culture into its style, for example party members attend Parliament assemblies in police uniforms, and the party's symbol is a tactical shield with a police cap above it, and a pistol and baton crossed in front of the shield, giving the appearance of a modernized version of Medieval heraldic traditions.
The party manages to win a landslide victory and starts incorporating new measures, such as a larger number of officers patrolling the streets, better salaries and training for the police force, and longer prison sentences for crimes.
How plausible is a development such as this? In which country could this most likely happen and when?
