Was on Rt 9 East Westborough going to Natick on the way to the mall with my boyfriend to buy him (ultimately) a Coach backpack. This tan Mercedes was doing about 10-20 mph in the left lane(traffic was light,everybody was going maybe 50-60mph) going through Westborough. Got around the car about where the exit to I495 is and seen some cracked out looking black female leaned over to the left gangster style talking to herself. Told my boyfriend she is just making sure everybody knows she is black by doing this massively overt passive aggressive shit driving. As I said, I passed her around the I495 exit and didn't think about her again. Then all the sudden around the Ford dealership on East Rt9 she passed me up and everybody else and starts weaving all over the place and slowing down again to almost 20mph in front of me. Got into the right lane to pass the crack whore again and looked at her while cursing using my best racial insults. Not yelling at her,just in my car,and not really yelling,but angry talking lol I was so mad I dialed 911,told the story,gave them plate and driver info.They transferred me to Natick PD where I was giving them precise locations and they asked my first name and phone #. By that time I was coming up to the Speen Street exit and had to take it,did not feel like following her and finding out what happens. So 2 questions..Is the PD going to come to my house and raid me for calling the police on a POC ? And how can I find out what if anything happened ? I really believed she was going to hurt somebody. Normally I don't GAF what somebody does as long as they only hurt themselves,but when other lives are in danger,I spring into action !
