If Juno were found to have not called for backup she would probably have to go into the station to fill out some paperwork or debrief to a superior what happened, but there wouldn't be any reprimands involved.
The main complications would be 1) involvement of the police in the supernatural which is dangerous for them which Juno would like to avoid, 2) Juno possibly being seen with supernatural allies by mortals which she would then have to try to explain, and 3) a possible distraction of having to go do something (paperwork, debriefing, reporting to superiors) that isn't directly related to finding Sandra.
As for the post, write a bit about Juno driving and make a roll. For reference,
here is the route taken so far in the chase. You've driven down Delano Drive, and in this upcoming post you'll be following the ghouls down Howard and onto College. Feel free to roll your Driving then match the description to the roll. [MENTION=478]Thanee[/MENTION] should do the same for Keira, btw, on her bike.
You can either post the complication arising (sirens, lights flashing, and all that good stuff) or you can leave it to me in the ghoul post following. I'm fine with either way. It's your compel, after all, so any way you like it, so long as there are police joining in on the fun!
I'll post up the Google Maps link in future posts as well if you find it helpful.
