Bugs

 * If already established as a Minuteman settlement, the quest target may show as Jamaica Plain (possibly other locations as well) settlers. Killing the targeted settlers doesn't seem to affect anything and the quest is completed as normal. However doing so will also potentially affect the standing of whatever companion you're with. This is the only way to complete this mission on consoles or by destroying the Institute. This can be done on PC though there are commands to bypass this, see below.
 * If the location you are sent to is a settlement this could trigger the targets to not exist as mentioned in the bug above. Upon arriving, the quest marker disappears with no targets to be shown. To fix this type in the console . This will complete the stage where the targets were to be destroyed, though were unable to. After this you will be able to hand the quest in and proceed to the next one. If this happens again, repeat the same console command as it uses the same console code for every location.
