Riding-in-tandem

I was interviewed by ABS CBN staff for the Ted Failon segment. The topic is about "Riding-in-tandem".
The term was used and is being used by the media and the police to describe criminals who use a motorcycle (but they can also use a car and "riding in tandem"). The first set can use it to snatch somebody elses bag. The second is to hunt for their targets, these are the assasins or known in the parlance, "cleaners".
We have to be cleared that riding-in-tandem is a methodology to pursue an criminal intention.
In prosaic description two person in same or difference sex riding on their motorcycle. This is riding-in-tandem.
The interviewer asked me if there will be an increase of this riding in tandem, what could this indicate and its implication? It they increase, perhaps the methodology is good in their business transaction. Second, it can be an ammunition for the opposition groups against the incumbent.
