We do have the technology. At ranges below 100 metres, a decent goose gun will do the trick.
A drone flying higher can be severely affected by flying a helicopter over it; the downwash will likely down the drone. Of course, you first have to find your drone, then clear all air traffic, then launch the helicopter and by then the drone operator will have achieved what they wanted to achieve (total air traffic shutdown) and likely scarpered.
