Availability of recourse to small claim under MAGenLaws I/266/120D

I parked in a 5-space parking lot of a business across street from my residence during a snow emergency when no other options were available. The business has been abandoned for some 6 months and there was no signage posted in the lot. Vehicle remained in place for some 4-5 hours, along with other vehicles similarly situated. Landowner towed my vehicle 5 miles away, and subsequently (the next day) posted 'no parking' signage before I could take photos. Alternative towing services/lots exist within 1 block of the location of my vehicle. I am interested first in the viability of a small claim pursuant to MA General Laws ch. 266 sec. 120D, given the lack of signage and inconvenience of the tow location. I inquired with municipal police as to the propiety of the tow and whether their department would agree to testify that the lot was unposted at the time of tow. Police department referred me to MA General Laws ch. 266 sec. 121A, which appears to be irrelevant to questions of civil relief. (?) If 266/121A is indeed irrelevant to the towing of my car, and I procees to small claims, will the police then be able to issue me a fine?
