Week In Review: Rahim Investigation, Democrats Divide And Electronic Tolling

We'll look at the week's news with our week in review panel.

First, the Suffolk County District Attorney's office concluded this week that Boston police and the FBI were justified in last summer's fatal shooting of a man who was under surveillance for alleged ties to a terrorist group. District Attorney Dan Conley announced Wednesday that police acted in self defense in the shooting of 26-year-old Usaamah Rahim. The attorney for Rahim's family, Ronald Sullivan, called for a follow up investigation and some civil liberties groups are calling for an independent investigation.

Then, we'll discuss state Sen. Jamie Eldridge's email this week urging the progressive wing to "take over" the party and to unseat conservative Democrats. This comes at the same time as Vermont Sen. Bernie Sanders launches a new political group Our Revolution to advance his progressive message after this election.

Finally, Massachusetts transportation officials are planning to start all-electronic tolling on the Pike at the end of October. The new system is capable of alerting police about specific license plates or transponders, causing critics to worry about how the information would be used and how it would be secured.
