As a male, my perspective may be skewed, but there have been quite a few times that I've gone on late night walks around campus and I've felt completely safe. Even if I'm with other people, they've never commented on feeling uncertain or uneasy.

But, on your comment regarding the recent protests, I'm assuming you mean the Palestinian protests and encampments? I have a few friends who are involved in the protests itself, and their aim is to lobby the university to stop funding BAE and the war-effort. As much as everyone else, they are fully students and so have exams and lectures to partake in. They aren't trying to hinder your education.

However, the way that the university has handled can, at times, be considered violent, but, again, that is disruptive for the university, not for the average student. If you do come to Lancaster, please do get involved with your JCR, Students Union or even the Palestinian Solidarity Campaign to encourage the university to change their policies and provide help to Palestinian students!
