The first problem that Betelgeuse had to overcome was visibility. In the real world Betel was a sizable man of six foot three weighing in at about 250 pounds. Back in the year 2012 he could have walked into a Walmart and disappeared like any other nondescript dude in his late twenties but the case was much different in the infected future. In the modern day people only left their houses to get supplies or to travel to the houses of close family members while any other trip was met with great suspicion and interest. To add further complexity to the situation the majority of families had been setting up exterior video surveillance. Even though there were very few people on the street, spending all day and night indoors was beginning to exacerbate America's dormant paranoia. A highlight of many weekly family conversations contained stories of the same stray dog who wandered from one camera feed into the next sniffing and pissing his way through the neighborhood. What this all meant is that it was hard to go outside without being detected and it was equally difficult that once you were detected to keep the nature of your business a secret. There was simply no way that Betelgeuse and fifteen of his closest internet friends could go on quest to a government owned jail for zombies and not be seen.
Luckily the answer was simple. According to Murkin the government wanted to keep their forced zombifications under wraps which meant that they would not openly arrest a group of people and poison them with the disease. Each member of the group self shot a video describing their current physical condition and their suspicion about the government infecting them. They claimed that should they or anyone in their party go missing that the government was entirely responsible. After the personal logs were made they were given to family and close friends to hide for safe keeping. The only thing left to do was to figure out how to get close enough to one of the prisons without being stopped.
