I believe the main reason that campus departments utilize Sheriffs powers is because as an SSPO, you are restricted to the property basically owned, leased or under control of the college or university. Which means if something occurs off property, unless it falls under "fresh and continued pursuit", or its a blatant felony in your presence, theoretically, you could not act upon it. As sheriffs deputies, your power to act upon something off of your property is enhanced. Even though your powers are restricted by statutes, you would be protected if you had to act upon something. The idea of seeking Boston SPO powers poses a problem for campus police departments because under rule 400, SPO's may not have the word "Police" on their patches, nor may they wear dark blue shirts, must have a red stripe, etc. There are advantages to both of them, but I figure SSPO and Sheriffs powers are probably the best combination.
