Just FYI, there have been some recent break-ins and porch robberies in JP and Roslindale. My thoughts on it:

At a  minimum, offer to take your neighbors' packages inside when they aren't there and ask if they'll do the same. Or get a post office box to have packages delivered to.

Use rods or window stops (sold at hardware stores) to make it harder for someone from the outside to open your window while not making it that much harder for you to open the window…
