The idea got the team discussing in-home security systems, which Parker views as a "big scam" due to the rarity of the system alarming for a real emergency. Parker and Stone spoke to a close friend who is a policeman, who confirmed that they received false alarms "all the time." The United States Department of Justice estimates that between 94% and 98% of all alarm calls to law enforcement are indeed false alarms. Several scenes were completed before the run began, with "Insecurity" set as the season premiere. Scenes scripted at this time included Cartman's dialogue back-and-forth with the security company employees, regarding his password. The storyline was still incomplete when its broadcast date neared, so they decided to wait on it for later in the season. At one point, they considered splitting the episode into a two-parter, between Cartman's battle with the security companies and the plot line regarding the postman. They decided to keep it one episode when they scripted scenes with the old man in Skeeter's Bar, feeling as though his dialogue connected the two stories enough. Parker remarked that the episode was inspired by his own life, when he had ordered items from Amazon.com, only to forget what it is when it arrives. Likening the surprise to Christmas morning, he noted in the episode's DVD commentary he has a tendency to order random items when "South Park" episodes are near completion: "I [order items] the most on Tuesday nights, when we're approving animation like crazy, it's like three in the morning, I'll just get on the computer and start ordering shit from Amazon […] just to make Thursday [its arrival date] like Christmas." The episode references Bane, a character within the Batman universe, specifically, his depiction by actor Tom Hardy in the 2012 film "The Dark Knight Rises". It also references UPS and Amazon.com.  Ryan McGee of "The A.V. Club" gave the episode a B, writing that the episode "did its best to link up the fear of cuckoldry with the fear of home invasion, but the results themselves were mixed." Max Nicholson of IGN called the episode an "admirable entry" for the season, though noting "While the plot here was clearly framed around recycling these two jokes over and over, they were both strong enough to carry out the 22 minutes in full."
