The Russian intelligence offers traveling on fake passports involved in the recent Skripal poisoning case didn't care one whit about the UK's customs face recognition, or omnipresent camera systems, and they were up to something far more nefarious than this.
Ummm...the Russians are on a suicide mission of sort. Do this and stay in mother Russia for the rest of your life, if you don't get arrested. They have a powerful nation state behind them and one that does not extradite its citizens. Even if regime changes, its very unlikely that they will be surrendered due to bad precedent.
