I always carry my own luggage, rather many a times one has to push off these porters coz they try to take the trolly or luggage from you.
If teh porter does not like carrying the bags or cannot handle them properly then he shud not be working as a porter. He shud find another job.

But...thats not the point, the point is high handedness of police. "if" the accusations are true, then this guy shud go to court, its inappropriate for police to kick and push the guy just coz he had a heated argument with the porter.
