I have figured it out

I think everyone needs to put the goverment murder conspiracy aside. It's the USSR in the 50s! If someone in the goverment wanted them killed they wouldn't follow them out to nowhere. They would just send officers to take them away from their homes. They were already being hassled by police on their way out.

Good points. Why would anyone want to risk there own lives in that hostile environment when it would be so much easier and just as effective the way you suggest.
